Would I be able to fit an XFX 8600 GT in this case? Do I need a low profile bracket?
if there is a pci-e slot
yes
I'm not sure if it needs a low profile bracket though........
it looks like a regular sized case to me
so it seems like it would fit
It will go just fine.
Me and my mate managed to get a 9800gtx inside a matx hp case so... XD
Sure you can, it would be easy. I have a A113W case and I can fit my 4870 in there (just wanted to try) but currently I just have a 9600 GSO in it. (this is heavy modded, new mobo, CPU ram and all, just the case is from HP)
So could I fit an HD 5770 in there?
measure your case first, for sure. i cant garuntee it.
