Smallish "gaming" pc

[blackball3242]

Looking to build a pc using a mini itx case so as to maximize portability for around ~500-600 . I've looked at a few cases that seem suitable.

I've narrowed them down to these cases

An sg07 is possible, but the case is a bit pricey.

I know these cases are small and have pretty weak psu's, but I'm not expecting to play most newer games-though being able to play max payne 3 would be nice. Besides that my goals are to be able to play Mount and Blade Warband near highest settings.

Looking for advice on the gfx card, as I haven't been keeping up with the market recently and don't know the current "sweet" spots. Looking to spend 50-100 on the gfx this time around.

Some goes for the cpu- looking to spend ~100-150

Again, these are some pretty small cases- so can a "gaming" pc be built using them, and more importantly- should it be done?

I would go for the Pentium G620 and the HD 7750. The power consumption would stay very low which is good for a smaller build (to keep the heat/noise down). You should easily be able to get those in budget and they should be fine for ultra high settings on games like Mount and Blade. For that combo, a decent 250-300W PSU would be fine.

Okay, my brother has an extra gtx 560 that he said he would be willing to give me more my build. Instead of buying a new gfx card, would it be possible to use it with a mini itx cases, maybe with a psu upgrade?
