Cray C916 scratch build - NAS case

Recommended Posts

Cray supercomputers are probably not a new name for anyone.

As on my other builds i make something strange or odd, so will this be :)

I´m not sure yet if i´m going with a ITX motherboard for it or taking a NAS and remove the case from it. The future will tell :)

I have eight 2TB S-ata drives waiting for a housing, dont know if all will fit but atleast 6 of them.

It all started with a email to CRAY asking for measurements for their old computers and casings

Then i told the story, im a fan of older big computers with some soul in the case and wanted to make a working scale version of it.

I get alot of questions why and how i can manage to keep all this projects alive, and why i dont make one done before starting another.

So here it is, before i get the same question again ;)

I do not have a job after a heart attack and a back injury, im at home with my 4 y.o. kids and the hours when they are on kindergarten and late night i need to fill with something to do (except for my company i spend some hours on), and there it is. I have probably 10 times more time for this than other modders.

Enough of the text, here my first sketch of the C916 based on information i got.

I still need to put into some more changes and details for it.

Rough rendering

My first idea is to have the drives standing up, two in each corner of the case.

Haha, Dubai maybe have taken some feeling for design from Cray :)

Did some planning, i will probably go with a ITX mobo and six 2TB drives. I have a 3-ware raid card somewhere in low profile that fits pretty good. Now i have the basic footprint size done, time to cut it in 4mm acrylic :)

2x120mm fans in front of the harddrives pushing air in, over pressure when the case its not air tight it will work perfect.

exellent idea..... my friend chad had photo of him standing next to that cray computer on facebook, but I'm having problem finding it.

Post it if you find it :)

Sun, Cray and good ´ol stuff like that are real porn!

HCP - It's funny you mention all the projects, before I read that part I was thinking - MAN Just how big is your work bench? More power to you. I seem to do that on a smaller scale. I'll be working on one part of my case and then start another part before finishing the other part. What ever keeps your imagination flowing and I'd say you have got plenty of that! Cool stuff.

Did some templates for cutting the acrylic and noticed one crucial part... The PSU.

So, instead of cutting panels its time to check up a PSU that fits into this creation.

I know i know, planning first, making later :P

I have 140x90cm "floor" space and about 20cm high, i probably go with a SFX or TFX from Be Quiet!

The SFX measures 125 x 100 x 63,5mm and the TFX 70 x 85 x 177mm, probably need to run the power into the case as its impossible to fit the PSU to a panel for connecting the power cable.

5 minutes rendering, dont know why i rendered it in the first place, but here it is :P

The white box is the SFX PSU size.

How much you think it will need in load? You can always check out the picopsu alternative. I had on that was 150W.

Need to calculate the effect for this beast, 6 drives + itx mobo and a 3ware raid card may exceed 150w, but probably work okay on 350 SFX.

Will check up the drives when i get to that box, dont remember what i ordered :)

It begins...

This is the base i going to add fiberglass to

ops, out of focus. Better pics later when its cut to size and braced.

Started out with making a template for the shape.​

Its only half, i flip it to get 100% accurate bend on the part im cutting.

And the tops parts done, time fore some gluing!​

The smaller ones are internal to hold the front pieces. (need 20 of them)

Some more parts cut in acrylic.The case will NOT be transparent, i use it to get stiff plastic to hold it up.

Time to start gluing the puzzle :)

Hmmm my kind of puzzle ;) am eager to see how the hardware is getting stuffed in it, and how it will be accessible for maintenance, will be posted for more

Dont have any hardware yet, only the drives. Still reading about intel atom and other intergrated CPUs on itx-cards. Probably order next week :)

More puzzling :)

And, one of three almost done.

This is just the external shape, internal they will look different depending on where it goes.

nevermind the pipe, the real one is drying from fiberglassing :)

And the real one

Really advanced gluing, got to make some jigs and parts to get spacing correct and at the same time angle in two dimension at the same time holding it so the glue could bite :)

Not sure if im satisfied with this, will see later after the internals of this parts is there and some paint.

Some parts missing, its 1.25 AM here so my neighbours probably dont like me starting the table saw :)

More work laters!

The one part where the drives go. Only one fan here.

Primed to see where i need to make some changes...

Its still missing the front panel that goes outside of the fan.

Its coming along pretty nice now :)

And this is what it looks like after 8 layers.

Now its time to let this cure over night, and tomorrow add some wood and plaster reinforcements to it before i take it off the pipe.

In that area i will only use about 3" wide, im making it big now makes me cut out the best part to use for the mold later.

And...!

Be Quiet! helping me out with PSU and Silent Wings 2 fans for this case :)

I have used Be Quiet! in alot of other cases and i totally love their products, i love quiet pc´s and i will go all in on Be Quiet! in my other cases too.

Thanks guys, still soldering on the WOPR, nothing to show. Its 1800 cables and over 5000 solder joints and a couple of feet shrink tube :)

Making the Cray as relaxing from the soldering when i need a break :)

Made top and bottom for the Cray today and started to put the "roof" on, pics later when the glue dried :)

My camera light didnt start so i got to pitch the contrast in the pic.

Just a smaller "right-now" status, top part drying.

Sanding the rounded top now and going to fiberglass it tonight to get that one done.

Here its more easy to see where the parts from the fiberglassed pipe is going.

Took me a great deal of time to get all angles right.
