I have about a $400-$450 budget to put together an emulator PC capable of running NES, SNES, Sega, N64, PS2, and Gamecube games. I'd like to keep it small enough to fit in my TV console hence why the HTPC's came to mind. The only games I want to play for Gamecube are Smash Brothers and maybe some of the Mario games, that's it. Any suggestions for this type of build?
