I've had a CyberStorm PPC running in my A3000 for about a year now. When I bought it second hand the spacers weren't included. Right now the only thing holding it in place is the CPU slot. If I give my desk a good whack the whole thing goes into a reboot loop with a yellow screen, requiring a cold boot to recover.
Searching these forums I can't seem to come to a definitive answer as to where I might acquire comparable spacers. Does anyone have any suggestions?
