I've got two machines that work pretty well and I'm bring in a new machine. PM me if you'd like me to go into detail about the machines. The B&W works really well, but is missing hard drive bracket. PM 4400 is maxed out on ram and is in good shape, except that pram battery died and I 'Made' a replacement from radioshack parts. let's just say I don't foresee the battery dying anytime before 2015 ;-). anywho, I need to move one of these machine to make room for a new (to me) g4.
