Put an SSD in there and you'll be amazed how quick it getsPicked up a 2007 iMac for cheap (couldn't resist) which had 1gb of ram and had OS X 10.5 / Windows 7. Upgraded the ram with a 2gb chip (3GB now) and then the OS to Mountain Lion but kept Windows 7. Connected my E-Blue Cobra Jr mouse, Logitech K750 keyboard and Logitech X120 speakers. So far it's a quick machine and runs great!
