Hmmm, was going to edit the "part 2" post, but Chrome won't let me.
OK, so here's a shot of the view behind the motherboard plate. I did tie up the sata power cables, but the other ones don't have enough slack to go anywhere. The USP-100 has LOTS of extra room where it really counts. Behind the motherboard is one of those places!
This shows how close the 9800gt is to the PSU. Unexpectedly, both the 9800gt AND the psu are cooler in this setup than before. The 9800GT was in F3 for a while, but I swapped him out for GPUs that had their own power connectors. This 9800 was part of why I blew up that other PSU...
The warmth coming out of the psu in the bottom mount is much less than when it lived at the traditional top of the previous F3 case. This pic also shows how I took off the bent double wide face plate from the 9800gt and put on the zotac gt430 "tall" faceplate. The GT430 that came with this plate is in the "office" rig, using low profile brackets.
And a shot of the rear panel. Even though F3 is running Vista Home Basic, I don't need any dummy plugs on the other GPUs. I'm not sure if this is common knowledge now, but in my readings, I saw lots of people using dummy plugs, and one folder blamed it on Vista.
I believe the F3 rig is at a stable point right now. Note that the GTS250 is missing.
Well, I was having a heck of a time getting the system to boot up ... no video anywhere. So I took out all the cards and put them back in (with the new GTX460 first!) and found that the GTS250 was acting up. But it worked. Then... it was like 100 deg C at idle. Ugh. I took it out and in went the lower PPD GT430. I need to reapply TIM for the GTS250 and then I'll swap them out...
As if that wasn't fun enough, suddenly, a jet was taking off from the rig. The CPU was cresting 60 deg C and the cpu fan was maxing out at 4000+ rpm. Huh... it worked before, wth? I shut down and took off the cpu cooler on there (was stock one from x6 1055t) and put the H50 on there that I removed from the CAD rig. I wasn't impressed with it on the CAD rig and I'm not on this one either. My Zalman cp9700 (on my F1 rig) works twice as well as this. The big Cooler Master Hyper N520 on my CAD rig is about the same as the H50, but only 2~5 deg C advantage to H50.
The bracket holding the fan above the CPU is a zalman 92 mm fan with mounting bracket. It's pretty slick, bolts up above the expansion cards and floats the fan where you want it. I'm getting more screws tomorrow on my way into work so I can set up push-pull on the h50 radiator and then I'll relocate the bracket so that it's back more over the RAM.
