directron.com has the Cooler Master Aquagate ALC-U01 on sale for $128 (I think it's the pre-LGA 775 version, hence the discount). If I were convinced I could buy one for my upcoming Athlon64 X2-based system and get away with running it at sub-24db "low" speed in a matching Lian-Li case with water-cooled 15,000 RPM hard drive and fanless PSU, I'd probably buy one on the spot. As it stands, I'm not entirely convinced I could achieve all my goals with it at its quietest setting... but at that price, it's pretty tempting...
