I have two computers - a MacBook Pro (in my signature) and an iMac G5 (2.1 GHz, aftermarket upgraded to 300GB HDD and 2.5GB RAM). The thing's getting old - the SuperDrive in it won't burn discs (but will read them), and the internal iSight is completely broken. I currently use it with Tiger, for those old Classic games, but I'm wondering, especially with the possibility of it not being able to run Snow Leopard, if I should just retire the thing instead. I was running Mac OS X Leopard Server on it for a while, and it works as a server - just not as well as I had hoped it would.
