- So the other day Jake was talking to annoying client
and about you know, what he wants his PC to be like.
And at some point in time,
they decided that instead of being in you know
a normal PC case would be a bill
that would take us you know, day, maybe 3,
they want a pyramid PC case.
So we're going to have to custom make it
using you know, steel tubing just like this one right here.
This should be the last of the supplies that we need for
this build right here.
But holy crap, do we have a lot of to do,
it's what 2:30 on a Monday, and by Friday,
we want for the frame to be built, the parts to be ordered,
and like a test fit, to be totally complete.
So let's take a look at what we've got going on over here.
So I've just mocked this up.
This is basically what we're thinking we need you know,
probably three GPUs.
There's only one in here right now, but that's fine.
You get the basic idea of what I'm going for.
This can be tricky to bend, and along all of the outside,
there's going to be Illuminati stuff,
(upbeat music)
- In about 15 minutes or so,
we're not gonna be able to change any of this.
We're gonna start cutting and welding and so on.
So if there's any thoughts that you have,
now is the time that you know, speak.
- How big is the base?
- Base is 26 inches
- 26 inches.
Can I have a measuring ruler?
- Measuring ruler.
- That's still pretty big in there.
- Yap.
- Do you think the client is going to be okay with that?
- I think he's gonna have to be.
He asked for a pyramid and this is about as small
as a pyramid can get.
Like if you look at this here,
there are a lot of spaces but not a lot of space,
that you can put useful things.
Like we're losing so much space,
just kind of like down in here, because is a trying
to down shape.
- Well, the customer's always right.
- Yap, he asked for this, we're gonna give it
to him for better for worse.
There are really three things
that you need for a good weld to happen.
So the first is, just well-prepared parts.
So these right here,
I've no grounding cut and also wipe with ice pro ball call
so they should be nice and clean.
You also need the knowledge of how to weld.
So I took a couple of welding classes several years ago,
but 3, maybe the biggest one is practice,
which I don't have.
I did a tiny bit of practice here.
Yesterday, some of them turned out good.
Some of them did not.
I haven't really tested TIG Welder in like, 3, 4 years.
Guess, this is the practice that we're gonna get here,
whatever.
Cannot be sold with a bit of persuasion,
probably some angle grinding.
It's not gonna be fun for me.
But at the same time, we just gotta it.
When you're welding,
you're basically just melting two pieces of metal
and if that molten metal gets exposed to the air,
really bad things happen.
So a pretty good example of that is here.
I still had some good old shielding gas, we're using argon.
And this, this well looks fine.
Come over here when it started running out.
Doesn't look quite as good.
Overall though, it starting to come together,
all that we have to do or make the bits that go you know,
from here up to here.
So what we have to do for that,
is use the Cobra Miter Daddy.
Basically the Miter Daddy is just this, nice piece of CNC,
that I believe it's aluminum,
that you're able to chuck up in the Mill,
and then set it at kind of whatever angle you want.
Then you have your piece of stock,
just goes in here like so.
You tighten that down and then you take your
Hole Saw which I actually haven't even taken out
of the package yet
Drill down to give yourself whatever angle you want.
The angles that we need to hit for this all to go together,
it's like half the complex one,
which is where the little angle cube is just incredible.
So you see it's totally level here on device.
And then we're able to take that, set the angle,
and this plane, it's supposed to be 26.4,
so it's not quite there.
Good enough for now and then in the other way,
it needs to be 42 degrees.
So that's right about, right about there.
Now with those two angles, after we tighten it down in 3D,
this should be in the correct spot.
(metal cutting)
Let's not look too closely at the welds here,
but you know the whole thing is together,
I imagine, even if they're not the prettiest,
they're gonna be pretty strong.
And I think I learned a lot about welding them.
There's kind of like,
you can see here where there's just a lot of weld,
I sort of blew a hole through it,
and then in stitching it back together,
I feel like I really learned how
to take welding pretty well.
So here's the basic frame, but we need to be able
to put like the motherboard and the power supply
and everything in it.
And normally, I would do that sort of thing out of aluminum,
but I'm concerned like, one about corrosion with just
touching the steel and two, we need to ship it somewhere
and it might just pull out.
I've seen horrific things happen to PCs and shipping.
So we're gonna try and use steel.
All right you wanna come over here Andy.
Been running a couple little tests
on the good old router here with cutting steel,
and I think I've come up with
some pretty successful settings.
So let's try and cut some steel on the router.
It's a bit more tricky than you might expect
because although there are a lot of calculators out there,
they're normally based off of something you know kind
of like the big old Bridgeport here,
where the limiting factor isn't the rigidity
of the machine but just simply,
you know the power of the motor
and how much metal it can mow through.
That said, this has been quite successful.
I like my test cuts that I have here and I don't know.
Let's cut out some back panels, motherboard panels
and everything.
(rock music)
So the power supply and motherboard mounting panel is cut
an end and the original plan was to have these supports,
that one up to this like cross member attached to that
and then attach to the power supply support.
But I just don't really like how it looks.
So instead, I'm thinking that I can come in here
and kind of exist,
flushed to the support.
The only problem is that it looks like it might interfere
with where the power supply is going to be.
So we're gonna have to test that out
and see if it actually fits in.
Poor man.
I should have just not showed anyone this
and said this was the plan from the beginning.
Oh, this is going to be totally fine.
Heaps of space for the motherboard.
And you're probably wondering right now,
GPUs can't go here because power supply.
But that's because we have these
wonderful PCIe extenders from Camino.
So you probably see all of them
in the Camino RM video that we have,
but they look like this,
this is the end that the GPU will be on.
And on the other side, we have just this little guy here.
So that slots in just like so.
And then our data is carried over these cables here.
So the plan is for GPUs,
to be mounted,
right up here on the same plane,
as this like panel that's going to be here
and we'll cut a nice big hole in it,
so that you can see all 3 of them just
in all of their glory to support them,
I stole this PCIe bracket from an inward one case,
it came with two of them.
I'm not sure why, but it makes my life way easier.
So you'll be able to put four GPUs right in there,
will only have three but like upgrading is cool.
I think it's gonna be sweet for this to not look dumb,
a really crucial part is that the GPUs have
to be at the correct angle.
I could grab it from SolidWorks
but who knows what exactly it is.
So we're just gonna come in here,
got this wonderful angle finder thing.
I absolutely love these things.
And it is,
50.25 degrees or 52.5 degrees?
- Hey Linus, do you wanna see a computer?
- Oh I'd love to.
- So this is what we have so far.
- This is actually not bad.
- Yeah.
- Given the initial plans that I saw,
this greatly exceeds my expectations.
- Yeah, I was kind of concerned that would just be garbage,
if I'm honest.
The only thing is the GPUs need to go in
and we have a bit of a problem.
And they need to be like, placed correctly.
- Aha.
- So if you kind of look here, we have conveniently,
two plates here.
- Aha.
- So that you can easily access them
cause it's gonna be just an absolute pain
if you couldn't do that.
- Aha.
- So we're going to be going in something like this.
- Cool.
- And you see it positioned something like that.
The only problem is I can't weld this in
and make sure it looks correct at the same time.
- Oh so you brought me for that.
- Yeah.
- Okay, so what we're looking at here
is a Threadripper 32 core processor,
probably 256 gigs of RAM because the client is insane.
He has no need for it whatsoever
but you can't talk reason with them you know.
She just wants to flex, right?
So we're gonna have either 1500
or 60 probably a 1500 watts Seasonic right?
That one. - Yeah
- Yap, okay, so the GPUs,
are all gonna be like sitting here in the pyramid.
And basically we're gonna have like, an Illuminati eye,
here in the front and there's gonna be like,
that's gonna be like a window,
and it's gonna look on to four Quadro GPUs because, again,
the client has an unlimited budget
and you can't talk sense into them.
So yeah, the customer is always right,
except when they're wrong,
and you just have to do what they say anyway.
Right?
- Yeah, I was thinking like,
we originally said we're going to do three I think
because it just makes more sense.
- Yeah.
- Cause I know you can do NVLink
and then like a Quadro for display, which is ridiculous.
- Yeah.
- But at least kind of makes sense.
- Yeah
- But I think it's gonna look so much better,
if you have four of them
like just the window and four GPU straight.
- So might just eyeballing this or what?
- Well, one, one second here one second here, Mr. Linus.
So first of all,
do you think this is fine right now,
or have it mounted in three spots like for the motherboard.
We can pretty easily add in some stuff out here,
is probably not necessary.
- I don't think it's necessary,
by the time you put a motherboard on it,
that will also serve to add extra rigidity.
I really don't think it's a problem.
- Yeah like this is thick.
- Yeah, I think it's fine.
Are the panels actually gonna go on here?>
- The plan is to just stand it off like an inch or so.
So there's going to be a gap along each side.
And then we have a steel mesh that goes along here.
You sort of tack weld that on
and then superglue some magnets to it.
So you put like the side panel on,
it has the gap that for one is going
to look cool and allow for airflow
and also allow for us to just,
ignore that this is not square.
- Yeah.
- And then you have the sweet mesh below it
and it's gonna be great.
- So we just pull a Tesla or like,
yeah the gap is a feature.
- Yeah.
- Okay.
- So now we need those in here.
- Oh, this is awesome.
Oh my God, that seems terrible.
- The key to a good weld is making sure
that you have a good position.
This is, this is not.
(cracking noises)
- Alright, you want to come look at the alignment?
You didn't even check it before we went.
- That's probably fine.
- What do you think?
- Yeah, seems good to me.
- Because we've got enough.
I kind of checked I made sure
this line was parallel with this one.
And then here, there's enough clearance for them
to pop out if we really need to.
- Yeah.
- So I think it's okay, actually.
With this tax in place,
we've actually got a pretty good look
at what the finished system
is going to look like in terms of the internal layout.
So I think we're gonna get away
with adding one more fan here.
So we're gonna have a total of eight fans,
the whole frame is gonna be on feet here.
So these fans are gonna be able
to suck air up through filters.
- Yap.
- Through filters, so we're gonna have filtered intakes
coming in on the bottom,
and then passive exhaust out these vents
that are gonna go down the corners of our pyramid.
And then,
for the cooler,
we were going to use that thermal siphon prototype, right.
- Yeah, now that I'm looking at it here.
- Looks a little cagey.
- I don't, I don't think it's gonna fit.
- Yeah, we might end up with something else.
Okay, we're gonna have some kind of cooler over here.
And then graphics is here
and because storage is gonna be just m.2s
on the motherboard, you don't actually have
to account for any additional storage.
I mean, really, it's just the only reason this is gonna
take up a 2 foot by 2 foot space on this person's desk is,
because they want a pyramid computer.
Oh, that's the table, not the computer.
- Yeah, the table is really not square.
If you guys are enjoying this build so far.
Maybe you'll enjoy I don't know should we throw
to one of our sleeper PCs.
- Sure.
- Yeah, sure, actually LTT Store playlist,
playlist of sleeper PCs.
- Yeah
- They're sick.
- Get subscribed.
- It's Alex's junk engineering at its finest.
- Yeah.
The workshops going away for construction a week
so part two will be very soon.
- Actually, yeah, we have to get part two done
or we will never get it done.
And then our client will be very sorely disappointed.
(giggles)
