I had a PowerComputing PowerBase (I think it was a 240 or something) that was not a bad machine. It was based off the 6360/6400 Machine, and I can tell you, do NOT use a Vimage G3 (or rather, get one) as it's not compatible with the video card. It has a daughter card, similair to the 604/603e machines like the 7500's and 8x00/9x00 machines. So if you can, find a G3 upgrade for one of those if you want to upgrade it.
I got an XLR8 MachCarrier which has a G3 Zif that you can get a Zif from either a blue and white, or a Beige G3 and throw it in it. But don't count on running OS X on it.
Also, if you need the software for the XLR8, i know where you can get it. just email me @

Let us know which clones you get. Some of them can actually be faster than the Macs that they cloned. Hence on reason Apple Killed them off:
Cheaper & Faster
