Just wondering if this is worth using for anything... I recently picked up a G5 Xserve, 16gb ram, dual 2.3ghz processor and 3 250gb SATA drives. Any functional thing I can use this for? Will this work as a time machine device or NAS or video server or are processor specs too bad. Also can I put in some faster drives? I.E. a SSD and terabyte drives in the other slots? Is it a power hog in idle? If I can't put it to good use I'll probably sell it.
