I have a P3 650E slot 1 with an ALPH P3125 attached to it. I removed the back and fabricated a mount for the screws to hold the heatsink on. I have an ASUS P3V4X motherboard. How do you get the retention thingy to really hold the CPU in? the little hook things that came with the ALPHA seem to no help much. Any one been able to come up with a good CPU mounting method for a P3 and ALPHA with the back off the P3?
