I have a number of these exact heat sinks on old disks up in the loft if anyone's interested .  I can't remember precisely how many, maybe 6 or 8.

I was considering cannibalizing one as a heatsink for a K1.

I'm in the UK and would happily swap for any parts / components that would help me DIY build a K1 nano or a fraction of a BTC to cover postage.

From the same server(s) I also have a bunch of 90mm cooling fans (12v 0.31A) if anyone can use them (I think I have about 30 of these!)
