One thing commonly not pointed out is Gamecube\'s height. Due to it\'s being top loading, as well as being an inch taller than Xbox to begin with, you\'d end up needing about 8 inches of height for it in your entertainment center. in fact, I might even have a problem as a result of that..
Shame it\'s too wide, otherwise I could stick it between my TV and entertainment center like I\'m doing with my upright-standing PS2 right now.
