Quote - I found out over the years that I don't upgrade computers. When I want better performance, I usually build myself a complete new machine, and relegate the older machine to less intensive tasks (or I sell it).

Same here. Except I don't sell my old ones, just move them around and use them for different things and distributed rendering. The PC I built two years ago is now a ridiculously over-powered stereo with my entire CD collection on it, taking up only about a third of its storage capacity.
I also have a ridiculously over-powered DVD player, since the one hooked to my TV died.  ;-)
