Socket 370/A Heatsinks (1U Copper cooler)

[RichardParry]

I am building a low profile 1U rack server, but I already have a powerful blower in the chassis (and the board I am using only has one PSU fan header, which I will use with the blower), so I would like to buy a copper 1U (low profile) cooler (no fan), I have seen a couple around (mainly on rackmount chassis manufacturer websites), but I need somewhere in the UK that I can buy them....

Any ideas ? Thanx!
