Well, the copper heatsink in the first picture is for the cpu's. I bought it from Small Dog for around $70, its OEM Apple for the dual 1.42 MDD. The heatpipe cooler is a Zalaman and is for my main ata HD. I got that from New Egg. The other HD heatsink is name brand (which I can't remember) and I got that one from New Egg too.
