How cheap is cheap? You can get a Mini for six or seven hundred. But you'll
need a screen, keyboard and mouse to go with it. I recently bought a new 20"
core2duo iMac. Not dirt cheap, but it's compact, quiet, has a great screen, and
is fast as hell. I think they're selling for around $1500-1600 now.
