Now that's a good idea PH, the mobo bowing can throw it out of true unless you have a cast iron socket
. I've been thinking of cutting a square out of alu to strenghten up the back of my graphics card for when mounting a block, I'd have to cut knotches for the resistors and SMT capacitors and line the bottom with an thin insulator. I want it to double as a passive heatsink as well though...
I've never considered the CPU socket though...
