Called up a computer store yesterday and asked if they had any trash/scrap heatsinks laying around. They were very cool and let me poke through their box of oddballs and take these two for free. Initially I was looking for both the LED and the driver, however since CPU heatsinks are so small I decided to build a heatsink for the LEDs. As for the driver I'll probably use the heatsink on the left, because the driver fits the copper surface area perfectly.
