Still, this barebones is something I will look at because I really don't need a full or mid tower. But is that power supply big enough for a 7950 GX2?
Well, just going by its wattage, I'd have to say no, but otherwise you'll have to get a technical 'brief' on the PSU, which may be hard to find. Newegg stocks this barebones system, and usually when they list such with a PSU, they take a photo of the PSU sticker, but in this case they didnt . . . According to one of the reviewers on newegg.com though, it does handle a 7900GT (If I recall correctly).
[EDIT]
As kind of a second thought, perhaps you could build your own Mini ATX system ? I do alot of looking around for small (ish) parts for compact systems, and if I recall correctly, shuttle sells bare cases, as well as many other companies. The hard part would be finding a powerfull enough PSU, that will fit the case, and remain unobtrusive enough to give you plenty of room, which can be a chore, but IS possible.
Here is the link for the compatibility parts for it:

According to it, no 800MHz RAM was tested and the video cards had nothing higher than 256MB RAM installed. I was planning on stealing her 7800 GTX 512 and give her a DX10 card when they came out, but now not too sure it would work (size-wise).
I'd like to build a SFF, but you're right- finding everything is a chore. And not too sure I want only 1 PCI slot in my machine.
I've seen one kick-ass case, a FrozenCPE HyperCube, but at over $400 plus options, it be a little much for even me. I will probably just go with a ThermaltakeArmour Jr. MaximumPC recently reviewed those cases and a few others this past month.
Or I could stick with my aging Antec Super LANBoy...ugh.
