i know this is probably posted a million times. sorry. well im gonna get a tbird 1ghz and cant decide which to get. the obvious retail gain is the 3 year warrenty. but its more expensive. and retail you save some money. This is my first computer, trying to get into makin them. gotta learn sometime. I'm just worried it will break or something then i will be SOL. also can anyone clarify heatsink/fan issue. when u get one retail. does it come already assembled on the cpu? if so can it be removed easily? cause i was going to get better cooling.
