I'm selling my Powermac G5 as I need more disk bays. I currently have 2 internal 1TB drives and 4 externals drives which is a mess. I need the new enclosure that has 4 internal bays.

But for a regular person without a storage addiction like myself, this Powermac is a powerful yet cheap entry to the Apple world or if you want to run a server (incl. Linux).
I'm adding a bonus: two *very* fast enterprise-class drives, Western Digital Raptor 10K RPM drives.

Dual 2.0 GHz, 1.5GB RAM, 2x 74GB (144GB) Raptor 10K
Full details in the eBay entry.
