This one still catches my eye though. 65W, but it's got 14.5ft head and "the lowest heat trasfer of any pump on the market" if the manufacturer's claims are to be believed. Also supposedly quiet. And at only $10 more than the MCP650, I'd wager it's worth a look. 10" long is a pretty big pump though. It might not fit between my hard drives and video card....
It must not be cooled by the water it pumps like a lot of pumps. This one is fan cooled, which probably explains why it doesn't add much heat to the water.
