Never had the guts to try a new OS. Recently I Got a Mac and have said never again to Microsoft.

Well my old computer is being used as a Home Theater PC (sort of) I have a All In Wonder card that I have hooked up to the TV. Now I dont have a fear of trying something new. But I dont know if my hardware will work with Ubuntu. I would love to dump Windows 2K Pro and install a new OS.
The W2K always crashes on me, even after new installs and the lot, its just not stable.
