I have an AOpen XC Cube EY65 sff pc. Currently with a P4 2.4ghz cpu which I want to upgrade. I can't find decent info on this pc anywhere. I updated the firmware to the latest I could find. Then I tried a Prescott 3ghz cpu and a Celeron D 2.8ghz. Neither worked. Surely these should work? Anyone else have one of these with higher specs?
