A solid 20A supply is a much better option than any PC power supply. You want a supply that will put out >= 20 A and not drop out of regulation.
In order for a 650W PC power supply to put out 54 amps, it would need to be able to do it all on the 12V rail(s). That's never the case with a PC supply. They ration the power between the various outputs. You might get 20A at +12 and all the rest of the power on the others. You really need to look at the specific numbers on the individual PC supply you have to know what it's supposed to do. Once you understand what it's rated for, you have to ask weather it lives up to it's ratings. Some PC supply outfits do live up to their numbers, others simply do not.

Ok, got what you are saying. I think though this kit is wired to run off a pc supply. Not sure but I think each device gets plugged into the various outs on the supply. Doesn't the arduino board use the 5v?
I've built a few gaming rigs in my time and was always impressed with the stability of the voltage coming out of good supplys.

I just ordered a set of prusa i3 kit (for 499USD, inclusive of PSU and other stuff) from www.3dprinterczar.com, estimated to ship by the coming week. The specs look pretty impressive and comes with free shipping, you might want to take a look.
