Let me start from the beginning. I bought a Sonnet G4-500 CPU for my G3-400 I use at home. Installed the software shut down swappped out the old and in with the new CPU and now up a running under the guise of a G4-500!! Cool I then convince my boss that we need to upgrade our G3s at work so he tells me to (based on my home guinie pig use) to order the G4-800 "NEW" CPUs OK. Install the software, shut down, unplug the G3 CPU and go to plug in the "NEW" G4 and.....ooops it don't fit I've included a couple of shots to proof this. The standard ATI Rage 128 video card that comes with a G3 almost touches the corner of the G3 CPU. When trying to install the G4 Its 3/4" to big to fit! Now I have a "non-returnable" CPU card and no fixes. I haven't had the chance to talk to Sonnet yet (maybe for the good, bcause I'm gonna rip someones head off) but when I do I thnk I won't be alone in this! https://secure1.sonnettech.com/stor...d=118&osCsid=a1b60875efc9dcd49cba15f839a3b6c7 Anyone know what I'm saying?
