    I question my own sanity.

    Putting everything into the case.

    [​IMG]
    I had to modify the bracket on the GTS250 on the end. It was a double height, now it's single height. :dremel:

    [​IMG]
    Fired up the system for the first time. It has no active cooling so I only let it run long enough to see that it worked.

    Excuse the poor cell phone pics :(

    Thanks! With any luck, I'll have it all up and running today or tomorrow.

    Hell yeah! I think I have 3 15" CRTs and 1 15" CRT lying around. There's also a 19" LCD that I could have used, but I didn't feel like disconnecting it from the server it's attached to.

    I requested a sample of conformal coating (for evaluation), it came in a 3 ounce bottle (the sample was free), I basically used q-tip stems to drizzle the coating exactly where I needed it. You would only need to seal where the cap casing meets the PCB to keep mineral oil from attacking the seal on the bottom of the caps.

    If the mobo is the only place that had cap failure then it's probly a non-issue.

    Worked on the case a bit more tonight but not as much as I had wanted. I really wanted to finish it today, but my electronics design lab is sucking hardcore, so I didn't get home until lateish.

    I decided to dedicate a fan to circulate oil directly over the GPU heatsinks. Seeing as how there are three GPUs, there is a lot of heat that needs to be dissipated. So this is the mounting bracket I made for this purpose.

    [​IMG]
    I bolted it to the top plexiglass "lid".

    [​IMG]
    And here it is again with the tray down.

    [​IMG]
    And from the front.

    [​IMG]

    [​IMG]
    I made installed these little pieces of bent aluminum to hold the wires going into the tank in place. I was having problems with them not staying put and the zip ties getting snagged, so these should fix that.

    [​IMG]
    I also made a new hard drive mounting bracket. The only difference between this one and the old one is that the drives are now mounted top side up (when the lid is closed). Previously, with the drives upside down, the sata and power plugs were so close to case top that I had trouble getting the plugs in. This fixes the problem. :thumb:

    It's almost ready! There are a few things left to do: mount the SSD, clean the tank, clean the aluminum, and probably a few other things I'm forgetting at the moment.

    Till tomorrow...

    could you not have mounted that fan to promote convection between the cards?

    Like under the cards pointing up? No room :( The PCIe 6 pin power connectors are in the way.

    that's a bugger. due to the design of the cooler on the 5800 series, where one end is open for airflow from the fan.

    [​IMG]

    Could you not lower the fan a little lower to take advantage of that?

    Here's the cutout for the SSD mounting bracket.

    [​IMG]
    And here it is ready to go.

    [​IMG]
    In place. I used some screws that were already in place so that I wouldn't have to drill and tap any new holes.

    [​IMG]
    All ready to be oiled up!

    [​IMG]
    Then I carried it up to my room (10 minutes ago?). The next update should contain some yummy oil pics!

    I also took the chance to weigh the thing:
    Me + Case = 204.5lbs
    Me: 132.5lbs

    -> Case weight (empty): 72lbs (33kgs).
    + 6 gallons of mineral oil: 40lbs = 112lbs. Yikes
    Not exactly a feather.

    Will definitely try to get a video up soon. However, it sprung a leak late last night (right before I went to bed) so I drained it. The tank is not leaking, and I doubt one of the fittings is leaking, so it's probably one of my temperature sensors or the bulkhead fittings. I won't be able take a look at it until I get home from class later today.

    Neither is difficult to fix, but if it's the temp sensors, I'll need to take some time to redo the seals with epoxy (instead of silicone) which would require me to completely clean the polypropylene T's. If it's one of the bulkhead fittings, I'll just need to tighten the nut or re-seat the o-ring. However, if it's something else (I don't even know what) it'll take more time/effort to fix.

    This is Houston, Liftoff confirmed.:hehe:
    I fear it might be that bead you added at the bottom of the tank.
