i guess you could go with the vantec aeroflow. from what i hear, it's a really good heatsink considering the pricetag.
i have a spire microflow ii, and while it doesn't perform as well as i'd like, it was $10 and cooled better than my other cooler master.
lostspyder needs to say more about this, but it looks like you need mounting holes for the slk-900.

I'll sort out asking around (so as to either get from Preston PC World or Manchester Mac reseller (and possibly get iLife '04 if it doesn't come with it)) and I'm going to get one on friday.. Only a 12" 800MHz stock version mind, but I'll bump the RAM to max as soon as possible..
