Hi there!
I recently bought this Acer after reading good reviews:
http://www.newegg.com/Product/Product.aspx?Item=N82E16883103795

The reviews said there was room for upgrades, but I think not! The PSU (I think) is kinda small. It's 5.5 inches (From back to front) by a little under 6 inches (from side to side) by a little over 3.25 inches (top to bottom). I want to upgrade it so I can get a better graphics card, probably an AMD 7790. Any suggestions for PSUs this size?

I doubt you need to worry about the physical size of the PSU. Newegg lists physical size in their "details" sections. I would, however be concerned about wattage & quality. IMHO, PSUs should never be stressed beyond 50% of their rated capacity. Yes, you will spend a little more for a larger PSU. Think of it as an insurance policy. Running a PSU at or near it's capacity is like driving your car in first gear all the time. It will work for a while but it's wearing itself out prematurely and it's unnecessary. FWIW, I prefer Seasonic.
