Alright, so keep in mind, it's a Silverstone SG01, so it's pretty small, but there is one great thing about it, there's a bracket over the video card area with a couple of fans in it. So the way I see it, I can blow air with the big 120mm fan into the case, and set the top fans over the card area to blow the hot air up and out. That way the air should be blowing along the paths it would naturally follow via convection. I'll have to test with the case cover back on after I cut a hole in it. Oh, and I did get a higher temperature reading after coming home from work and the ac was off, it got up to 55 degrees. I'm going to have to look into overclocking this thing. But anyway, here's a shot of what it looks like with the top fan bracket installed, and I've done a little wiring simplification:
With the bracket off, looking directly down on top, it looks like this:
So that's how it looks now, still working on the hole in the side, but I don't think it'll be a big problem, I've got the tin snips handy. I still have to velcro down the lower drive cage a little, I had two drives in it with a fan, but to slide it over enough to allow the card in I had to pull out the fan, cut the top off the drive cage, and move one of the drives to the free 5.25 slot. But it's all good now, and the 65W cpu I swapped in is running plenty cool, so it's been a great upgrade all around, really. And now I have an old quad core I can swap into a different machine for a core 2 duo, and the upgrade cycle continues.
