Here's what I ended up with. It's 30" wide, 24" tall and 22" deep.

Let's start at the beginning.

b9a2ed37d1ff6325d1eadb3c2945325c

Hand cut sheet metal.

daf31a2fe86d315ec69748b59c95c32b

Asus KGPE-D16 and dual Koolance CPU-360 waterblocks over dual Opteron 7372 CPUs, 128GB RAM and a GeForce 590

03b88ff09beb2cc0fbfe6a460d64d20f

The first rest fire. Worked great. Seasonic 1200w PSU in the background

d88ad05b31ac8e1f861b09687e4d395e

Test fit of the motherboard into the future CPU tray.

dc8385370826772fc5d24bd8fdba636d

Building the walls.

05e220e30e87e862c8e87351d8e64490

Cooling and Accessory bay.

1414a88c04797b7d9123928306ea7de9

Basic chassis assembled.

1d45cc301dc05dd30c3e2c7960cac535

Future cooling towers. 15" automotive transmission coolers. (yes, aluminum, I know. They are electrically isolated, so it SHOULDN'T be an issue)

fe449719bdd005108700da4b8bd7adae

NZXT touch panel 5-way fan and temp module.

72eeb95329272f1ab5ad30ba3359f65b

All disassembled and ready to install, plus flow meter, two temp sensors, two fans (not what I ended up using) and a MCP655 pump

9a52c5d36b4d62b857b69da2479039c8

GTX590 with XSPC waterblock, two WD Black 2TB drives, KGPE-d16/128GB/Dual Opteron 6372s, Seasonic 1200w PSU, an Agility SSD and the MIO audio card. for the Asus board.

I ended up going with different graphics, SSD and hard drives and dropped the RAID controller.

23a3bd9dfe7f630afa76b35ec683374b

350 TEC and heat sync (fan was replaced with quieter unit), and a whole slew of fittings.

328b8a43a3c7dcf8e9b3d50fce1c61a0

Hanging brackets for the cooling towers.

116e3abe0bb1cf0927d6c819a9aa8a17

Test fit of cooling units in glass cylinders.

c88bc8f2968a178c31d008f41164e5ac

Filed divets into fins for o-rings to prevent the cooler from rattling against the glass.

a496acf118e337a7f0e37d5b0976a066

O-ring in place.

41283c3cf6ea8749c0504749b520b9f7

And we have a cooling tower almost complete.

1704e0394bc6990928f9ac2996c4aa23

Test layout of accessory bay.

602335d0ac2b5bcb4fa3b8fa64bbfb53

Cutting the holes and reinforcing the bay.

664556c748c6f5b2601b891a91a57d16

First test fit of cooling towers, reserviors, fan control and TEC.

bb8c17c30c0917b83f57ff2d282e71a1

Another angle of the same.

4ccdef10bbf295090d274555c72abcbe

Test fit of motherboard on risers and copper tubing for cooling.

7264ea5e54ecb4306092866a077d5b08

All laid out to restart work after a haitus from building.

0256cd3eec288eac044c66e48d95c3ac

Full copper loop in place. The first loop was parallel, and was dumb. Moved to running the cooling in series.

9cc3cd8738d8c3dc046ed72144ec2e3a

I also moved to black tubing after one too many "That's SO steampunk" comments. Not exactly what I was going for. Almost, but not quite.

5ba439e075d7e2c4175629c04cf50a2c

Test boot.

24021293f32b4fe5671f043fd4a18b88

Testing the TEC.

003314ace2581136eb4ac11cfa091171

Lights and card bay cover being built.

2e572db835d4807be54a9ceaa0912484

Note the bypass outlets on the side. It allows me to purge, exchange or add fluid without having to breach the loop.

8c05bf1fd7a8868190454d130cdb4f97

First full power on after lights, etc. There is one piece of flexible tubing, in place where the second GTX 980ti is going.

Custom rear panel IO. 3d printing is fun.

ffcacd8756bf105ff282e8b6ed42db2f

Hot-swap SATA bay. Did I mention 3d printing was fun?

9328b25640be19cbb1754822c9402f02

The interior from the rear. The TEC is covered in insulation with the controller the grey block right next to it. The drives are on the upper right, the blue card is the fan controller. I'm sure you can figure out the rest.

940451ff642e362dfb58165cbc27c237

Complete system. Typo corrected, second graphics card added, card bay complete, and running like a champ.


Still a couple of Opterons, though I swapped for 6308s as they have higher clock speed (fewer cores), the drives have changed to Samsung EVO and Seagate 7200rpm 2.5" hard drive.

I'll be upgrading to an Asus X99M WS mobo with 64GB DDR4 RAM (downgrade in quantity) and i7-5930K in short order. Everything else will remain the same for the next couple of years.
 
The last picture has the second 980ti STRIX in place (was holding off on moving it so I could still use my other machine until this one was done).

My benchmarks really weren't where I wanted them to be, which is why the planned immediate upgrade.

The reason for the specs is that I do a fair amount of virtualization and performance tuning, but I still want to be able to game. So I figured, build the baddest thing I could for both worlds, that way I wouldn't have to build again for a couple of years . . only to find that it took so long to build that I have to upgrade right out of the gate.

The other upgrade it'll be getting is running a separate RAID5 array for the vm cluster, which I can suspend for times when I want to game, or just relegate to the top two cores if I still need them on.

The TEC kicks in at 40*C, and I have yet to see the coolant hit above 46*C, even under full load for several hours with OCCT running solo as well as on top of my standard workload.

The lower bay you can make out is for the two aux power supplies and optical drive. One aux PSU is a dedicated 24v for the TEC, the other is a 12v 6A PSU for running the pump when the system is off, that way I don't have hack around at it if I need to purge the loop for any reason.
 
Amazing work on that! I love the look of the custom i/o panel.

Also love that Dr. Pepper made with real sugar too! Got some of that in the fridge.
 
One word - WOW! Great work, it looks amazing. What are the specs on hardware - CPU, GPU, and RAM? What are you going to use this rig for? I see that it is a server motherboard and wondering what youll be using it for and the benefits of a server mb/cpu's are?
 
Do the cooling towers provide an actual physical benefit? What are the specs on that TEC chiller?

I'm interested in the cooling you used.
 
Your friend gave you some good advice about posting here. This is an awesome unique build and some good in-progress pictures.

The Dr Pepper is there to give a good size reference. The thing is . . . . not small.

And I prefer the sodas bottled down in Mexico. Somehow, they taste less syrupy and are more refreshing because of it.

Nice work drokicki! I bet turning that beast on felt goooood! :)

It did. That first test boot screen was great. Also, the first time the loop passed the 20psi test against leaks was a great moment. A LOT of potential leak points here. Figure every piece of tube has four leak points, plus all plugs, elbows, bulkhead connectors (9 of them), and on and on.

Dual Opteron 6308 (so 8 cores alltogether)
128GB DDR 3 Registered
Dual Geforce GTX 980ti STRIX
512GB Samsung 850 Pro SSD
2TB Seagate 2.5" 7200 drive

It is used for casual gaming, and a virtual dev environment. It lets me do both.

The benefit initially, when I spec'd the box several years ago was the capacity to do a VM environment, and power two GTX 590s (since retired those), along with dual Opteron 6372 CPUs. I changed to the 6308's due to their higher clock.

Though the upgraded specs are:
i7 5930k
Asus X99E-WS
64GB DDR4 3200
512GB Samsung 950 PRO NVMe
Everything else will stay the same.

The cooling towers do the majority of the cooling. The TEC rarely kicks on, and there's no other active or passive cooling on the thing.

The towers are 15" dual pass transmission coolers, in fit glass tube. The scoops at the bottom have a couple 120mm Corsair APs pusing air up the tubes.

The TEC is a 350w unit. It was a freebie that I got a while back. Thing works. The TEC only kicks on at 38 C. I've never had the water temp at the TEC controller (near the end of the loop) over 42 C, and that was with three vms, OCCT running in PSU mode, and Plex reindexing. Cpu temp at that point was about 51 C.
 
Very cool. Any plans to paint it ? Or just keep the bare metal look?

I'll be keeping it bare metal. I may build another one someday using extruded aluminum for the frame and just paneling the sides. If I do that, I'll likely have the side panels powder coated.
