My advice is to get a new Mac mini instead of upgrading. Use your working Cube as a backup or home server.

OWC has only a 1.8GHz Sonnet ($299) and a Dual 1.6GHz PowerLogix ($549). Unless you are a near electronics technician, I would recommend Tekserve do the switch--it's doable but tricky. >> B/ will a faster CPU enable me to run >> Mac OS 10.4?
