- I can't wait to show you guys this. It's finally here, my diamond play button. You're probably thinking to yourself, "Gee, Linus, you have like
13,000,000 subscribers. How did it take you so long to make a video about
your diamond play button?" That is because this is
a diamond play button like no other diamond play button. Guys, this is mother
(beep) Linus Tech Tips. This diamond play button
is gonna have a PC in it. Vincero wants to give you a chance to buy stylish watches

own diamond play button PC is, of course, getting
a diamond play button. The process is super simple. All you have to do is get you, 9,999,999 of your friends, to all subscribe to the
same YouTube channel. Then you request your
reward from YouTube directly and they send it in the mail. By the way, guys, thanks
for your help with that. Step two, finding a PC that will fit in a diamond play button. The X Y dimensions, actually
not that hard to deal with, but the Z height is not that thick by the time you factor in cooling. So we went with this Intel NUC. It's got support for an M.2 SSD, up to two slots of SODIMM memory, and this right here is a Core i7-10710U. Now, going with 10th Gen, we do give up Intel's
Tiger Lake XE Graphics. But, what we gain in return is six cores and, with this particular model, the ability to go real fast if we can provide adequate cooling. And, the reality of it is, guys, is if we really wanted
fast gaming performance out of this thing, we would use an external
GPU with Thunderbolt anyway. So this feels like a great choice. Massive shout out, by the way, to Simply NUC for sending
this thing over to us. They do sell this and many
different models of NUCs. Usually they look more
like computers than this so you'll have to check that out. Man, the job they did on this thing is- - [Alex] Oh yeah. - It's beautiful. Like, are these beveled edges? - [Alex] Oh yeah. There's
no sharp edges on there. - [Linus] This is unreal craftsmanship. But, we'll get more into that later. For now, I wanna show you
guys how the PC goes in here. So you see these four
standoffs right here? It's just going to go a
little something like that. And the reason that we
want to lift the PC up off the bottom of the play button is because that's gonna give us room to kind of jam our cables down there, and also give us enough
clearance to run our cooling over to this heat sink. IL access is right there. See that? - [Alex] Ooh, this is cool. - [Linus] Pretty much
everything I'm showing you guys today, by the way, I
am seeing for the first time because Alex did this project
almost entirely unsupervised. So, this appears to be my CPU cold plate. - [Alex] Yep. - And then these are presumably... wow, that's a snug boy fit isn't it? I mean, that's good for, you know, thermal transfer and all that. But these are heat pipes. (Linus exclaiming) Okay, so I'm gonna screw this
onto the CPU then, right? - Well, first you need to
put all the heat pipes in. And you asked for us to solder them. I don't know if you still
want to do that, but we can. - How much work is it to solder them? The thing about solder is that it needs to melt onto the surfaces that you're trying to bond. And the thing about heat pipes is that it's designed to
move heat away really fast. So, heating up a heat pipe enough at the point where
you want to melt the solder without heating up the
entire thing so much that it explodes, is a bit of a tricky matter. We've never really
successfully done it before. - Yeah, we should be able to do with that. - OK, smooth flow solder paste. - [Alex] It's low temp, may be possible. - [Linus] Let's do it. Before we actually put
that in place though, there's three more smaller
heat pipes that we're going to use just to spread the heat
out within our heat sink here. So the idea here is that
we've got heat pipes carrying the heat from
the CPU, transferring it to these heat pipes, which
spread it out in this heat sink. Now we probably could
have gone fully passive but we're going to add a fan too so this thing is going to
perform like pretty amazing. We hope. It's never actually
been fully assembled. I've never soldered a heat pipe before. - Basically just rough it up with a little bit of scotch brite. - [Linus] Is this kind of like a less is more situation
or do you even know? - [Alex] I'm not totally sure but you know that it flows
at 138 degrees though. - [Linus] And this is what people use for soldering heat pipes. I'm sure that I'm doing
this completely wrong. - [Alex] Is what I was
told by the internet, yes. - [Linus] Here we go. So... I mean hey, the good news is it's kind of like lubey
compared to before. Well no, it goes in a little easier. Alex, am I even sort of doing this the way you're supposed to? 'Cause that would be really good to know. Like, in the video where they
told you to use this stuff did they at all show you how to put it on? - [Alex] They kind of just put it on and put the heat pipes in. - [Linus] Well, I
definitely am doing that. - [Alex] It didn't look like this. (both laughing) - [Linus] Okay, I think they're in. So theoretically this will melt and it will solder this to this. Oh wow, look at it go. Holy (bleep), I think it's working. - [Alex] Oh yeah, damn. - [Linus] I wish I had applied
it a little more cleanly but we won't really see it. - [Alex] It shows on the flare that it's above 130 degrees Celsius. I guess it's high as this goes. - [Linus] I mean, that looks
pretty darn soldered to me. - [Alex] If you want, we
can also try soldering in the other heat pipes since
that seemed to work well but I think that'll take way longer. - [Linus] Yeah, I think
it might be okay though. - [Alex] Okay. - [Linus] I think this
is the coolest build we've done in a long time. It's the Linus ego build. - [Alex] I think that
was the gold controller. - [Linus] I'm going to be
like celery sticks, you know? Kind of spreads like
peanut butter too actually. We're doing two things right now. We're heating this up to
melt our solder flux paste. And then we're also heating
it up so that we can push out the plastic or whatever
it's made of, "diamond". - [Alex] Oh wait, we basically
can't thermal image this. - Oh, because it's too shiny. - [Alex] Yeah it's way too shiny. - You know what would be great is if we put a piece of
tape on it or something 'cause we really do kind of
need to know how hot it is. I think a little bit
that I could see melted, what's the temperature of the tape? - [Alex] Tape's 106 degrees. So yeah, you must be good. Let's also pop out the
button like very soon. - [Linus] Don't touch this, hey? - [Alex] Yeah. - [Linus] It's a little toasty. Okay. Oh, it's out. It is way deeper than I thought it was. - [Alex] Yeah. That's one of the reasons
that it was so hard to find a PC to fit in. - [Linus] While I wait
for this to cool down I can go ahead and remove
this electrical tape. Oh, that's leaving a nasty residue. Unfortunately we had no
choice because in order for our thermal camera to be
able to read the temperature of this reflective surface we had to put something
non-reflective on it which actually leads
into a really cool story. How on earth did we CNC
out a diamond play button without a CAD model? Well you can't. So we had to get one. Now the most obvious way
to get one would be to ask YouTube for it, I mean they designed it so they
should probably have it and they do. But unfortunately
YouTube's lawyers would not allow our contact to send it to us for the purposes of
modifying it to put a PC in. So we had to 3D scan it, which guys, is no mean feat because
the way 3D scanners work is they bounce light off of
the object and then record it in order to get all of
its shapes and curves and, oh no, this thing
is a fricking mirror. How do you 3D scan a curved mirror? You give it to a professional. So we enlisted the help of
Laman Designs in North Vancouver and Omid over there, I
don't know how he did it, but it fricking worked
and, great job guys. This is the raw scan file. How... (laughs) I don't even. This should be cooled down now so we can test if these are in. Oh! Ow it's still hot, but okay. Oh balls, does it do aluminum? Because it seems like
it just didn't really adhere to the aluminum. After further research, it appears that our NC191LT50
solder paste is not ideal for aluminum and copper. So we roughed up the aluminum again put a little bit more of it on this time and we're going to see
if we've got a good join. Otherwise we're going to
have to go to thermal paste or thermal epoxy. Actually I think it, I think it- - [Alex] Wow.
- [Linus] ... bonded. Oh, heck yeah. Ha! Woo! - [Alex] While that cools, there's two things that we can do. We need to put IO in here. This needs the chop.
- [Linus] Yeah. - [Alex] We're going to just
steal this, epoxy it in here. Oh, we need to solder the front
panel connectors onto here. - [Linus] Where the hell is
the power button going to go? - [Alex] Well, we kind
of get to just put it wherever we want because
the hole isn't drilled yet but I can go like here or here or here. - [Linus] What do you want for colors? I'm thinking I'll just do like a rainbow. - [Alex] Sure. Hey Linus.
- [Linus] Yo. - I just realized something. The WiFi antennas are
just hanging out in here. Should we take those out and put them in like a spot they might work? - Yeah, I would like to have WiFi. - For the IO, we didn't want to cut it into the actual play button because for one it's just
difficult to cut in here. And also, like, if you
get it a little bit wrong you're kind of just screwed. So instead, sorry Simply NUC, but the thing that you
sent to us is about to die. (tools scraping) - And pencils down. Are you done? - [Alex] Yeah I'm just
waiting for you at this point. - Well, I did a really good job. I don't even need shrink wrap. - [Alex] I think you should
still put it on there. - Can you please appreciate
that I did a good job and I probably don't need it? - You did a good job
Linus, I'm proud of you. Actually I just realized something. We should probably add some
like connectors or something to this because otherwise
we're going to have to install this power button and that board at the same
time, it's going to suck. - [Linus] Oh.
- [Alex] I have an idea Linus. We just take some of these male and female little pluggy chummies, solder them on to there
and solder them on to this so then when we want to put it together we just... - [Linus] So really I soldered
the wrong wires here though. So I'm doing completely
unnecessary soldering a wire to another wire. - [Alex] Well, but now you
can solder another wire to that wire and it'll be not that hard. - Yeah, just, I could have
just cut off of those wires. And then the connector would
have already been on them. - [Alex] Eh, details. So we now have to properly decide where this power button is going to go. - [Linus] Oh, this is real final isn't it? - [Alex] Yeah.
- [Linus] Ooh! That diamond cut out, that looks so cool. - [Alex] Oh yeah, it looks so sick. Especially with the fan underneath it. Where exactly do we want this? - [Linus] I dunno like here?
- [Alex] Here? You want it up here? I thought we said it was
going to go down here. - [Linus] How about like here? - [Alex] Here?
- [Linus] Yeah sure. (Alex hums) - Dude why did you ask me to pick and then tell me it's
not a fricking option? Put it wherever the hell you want, I don't even care anymore. (drill running)
- [Alex] That sounds good. I like this. (drill running) That's a nice hole. - [Linus] Check this out. We're fricking good to go boys. Oh God. Wow, that's really tight. That is actually a really
cool tool that I have never seen before and I love it. - [Alex] Wait you've never
seen a deburring tool before? - [Linus] Okay, that worked perfectly. Is this it, do we assemble?
- [Alex] LEDs. This is what we're using.
- [Linus] Wait, what? Light up your wonderful life. - [Linus] And then we're using this and the fan's also being powered by this. - [Linus] Wait, what? Why? - [Alex] Because the NUC
only does five volt for fans and there wasn't a five
volt fan that would fit in here correctly. Put it there, tape it or hot glue it. You take the next one, tape it or hot glue it.
- [Linus] Oh my god, that looks horrendous. - Well we could also have done a completely custom solution. - This is faster. - Yes. - There's only one way to know for sure. if these strips will bond to cyanoacrylate and that's to use my finger
and try and stick it to it. - [David] Maybe you should
double check with your hair too. - But what about we use this moment to- - Oh God that's a lot of CA. I don't think CA sticks to aluminum. Fortunately we have this
bond aid epoxy putty stick Alex wouldn't let me
handle this with no gloves. - It's not good for your skin. - So I just mush this up then? - [Alex] Yeah, should be a bit hot. - While I'm working on that
it's as good a time as any to talk about the actual
design of the PC itself. So what I'm holding in my hand as you can see is not made of metal. This is a 3D printed mock-up
so that we could do a test fit and also just kind of
a general sanity check. It's all fine and good
for Alex to create it in SolidWorks based on
that 3D scan that we got, but it's another one
entirely to double check, make sure the scan was
actually frigging accurate, and make sure that our
components are going to fit. So because our printer
bed isn't big enough we printed it in two
pieces and it was great. So from there, Alex was
able to send our file along with our diamond play
button to a bloke named Amish. This kind of machining is very out of our depth, at least for now, but holy frig did Amish
do a great job of it. Using his DMG Mori DMU 65 monoBLOCK, a five axis CNC machine with a whopping 46 horsepower spindle, it could have made very quick work of this but believe it or not, Amish went out of his way to make the
tool paths complicated so that the cutting would look extra sick on camera for all of y'all. One unfortunate thing we
learned while cutting though is that although the play
button is made of aluminum, and YouTube actually
told me that it is solid polished aluminum and nothing else, it has actually been electroplated in copper and then chrome. So what that meant was
that no matter how much we polished the aluminum
back panel we made, it could never have the same
super shiny surface finish as the rest of the play button. I do think that the cutout diamond looks absolutely sick though.
- [Alex] Oh yeah, so good. - Crap, even this epoxy came off. Nothing sticks to these stupid things. Look, it's not that we wanted
to use double-sided tape. - [Alex] So we wanted
to use double-sided tape and tuck tape. - [Linus] We didn't ask for this. (Linus gasping) How frickin' awesome does that look? We don't actually need this much of this adhesive to keep
the diamond in place. But what we're doing is trying to ensure that we have a consistent look to this shiny piece that goes under it. So we're covering the entire thing. (Bleep) it, I see what you mean about it being hard to get it like center. (grunts) - [Alex] Ugh, jeez Linus. - [Linus] You know what? We're rolling with it, Alex. - [Alex] So this is going to go here. - [Linus] We could like spend
an hour cable managing this but I really don't think
it serves much purpose. And you're sure this USB
port has enough power for everything that I've plugged into it? - [Alex] Uh, pretty sure. - [Linus] I guess that's
only six LEDs and a fan. That should be fine. Yeah, okay. Honestly, I think we can
just pressure fit that. - [Alex] I'm down. - [Linus] Yeah, like that's awesome. - [Alex] That's not going anywhere. - In a perfect world I
wouldn't use thermal pads for where we're crossing
our heat pipes here, but the truth is we don't know how
well this is going to work. So at least this allows
us to run the machine and validate the concept. This thing's sick. 32 gigs RAM. Well, it's not perfect by any stretch. I mean, for extra credit,
we could have soldered to these little tiny USB headers and put like an RGB controller in
it and stuff like that. But honestly, I am super happy with what I think is
about to be the result. Are we ready to close it up? - [Alex] I think so, yeah.
(Linus giggles excitedly) - [Linus] Fan's in. Computer's in, the IO looks amazing. Oh my God, that looks so sick. Man, been planning this build since before we even had
10 million subscribers. This is freaking incredible. Check out that IO, David. Is that clean or what? Alex, you did a great job of that. - [Alex] That is custom built. (smooth funky music) Let's get hardware and fill up here. Get Cinebench up. Oh my God. This is so freaking cool. My computer is a play button and my play button is a computer. Okay. We ready? Minimum test duration,
test for thermal throttling CPU multi-core here we go. Are you rolling on this right now? Because our load temps
are like 60, 65 degrees. Mind you, you know, we're maxing
out at like 2.85 gigahertz because this is a U-class
processor, but still come on. It's a play button. How quiet is it though? Oh, it's whisper-quiet. Oh my God, this thing
is so far beyond cool. Alex, you did an amazing job on this. This is nucking futs. Get it, get it. I don't even care that the
jewel has a crack in it. That just adds character at this point. What I want to know is
how much it'll turbo. Okay, CPU single core. Man, you could game on
this puppy fine, just fine. We are getting four
flipping gigahertz on it. Hold on a second. No no, hold on, hold on. Don't turn that off yet. We were hitting like 4.3, 4.44... We touched 4.5 for a second there. I think there were some background app updates that were
hitting multiple cores, man when this thing's gaming with like external GPU or something it's gonna be a freaking beast. I love it. And you know what else I love. I was going to segue to our
sponsor, but first you guys I know it took a while for
us to get this project done, but thank you very much. 10 million subscribers is
an absolutely unbelievable accomplishment that we
achieved a long time ago. And we really appreciate
everything that you guys do to make this possible. And we also appreciate our sponsor. The Drop ENTR keyboard is a
new keyboard from drop.com made, of course, with high-grade
enthusiast-class materials. It's got an aluminum top
plate with white LEDs so you can read the
keys in dark conditions. It's got double shot PBT key caps and weighs in at 964 grams so it's heavy enough to
stay in place on your desk but not so heavy that
it's impossible to take with you on the go,
which you just might do thanks to its 10-keyless layout. It's available in three colors with your choice of mechanical switches. So don't wait, buy it today at the link in the video description. I feel like normally when people do their 10 million subscriber videos there's a lot of like soul
searching and you know heartfelt talking at their audience. But the truth is, I think
I already did enough of that for like four YouTubers
plus their apology videos. So you guys can go watch that, to see how I feel about all of that. Today is just about being (bleep) cool. Like that's a computer. Ooh
it's warm, it's a warm boy.
Sorry u/dyajiv looks like it's not water cooled
