I have a Dangerden Socket A Maze3 copper top waterblock, but I just upgraded to a P4 setup. I could buy a new top, but that costs $20. So, if someone just went socket a from a P4 and wants to switch, lmk!
Also, in case you don't have a P4 block and still want mine, I'll sell it for $45 shipped with brand new mounting hardware (the plastic kind).
Heatware is available
here. I also have a couple eBay refs under the name Pakman117.
Thanks for looking.
