DAMN YOU for showing me that thread!!! Here I was, thinking I had everything just about sewn up and then you hit me with a solution like that... B*s*a*d.
Seriously though, that's a nice piece of kit, which would of course instantly solve my space problems so thanks a lot for the link! The price inc. a full kit is a bit prohibitive, which means I'll really need to do some serious thinking, but a fully external solution like that is quite tempting.
I still think I'll come down on the side of an integrated solution in the end, particularly as I really don't need truly state-of-the-art cooling performance. A few extra MHz is always nice, but so far I'm very happy with my P4 1.6GHz, which is happily chugging along at 2.24GHz at the moment (it will do at least 2.4 without complaining, but only with a single DIMM. However, a change of MB will soon take care of that).
I should, of course, have explained my system config to start with, so I'm to blame for any confusion over the space issue.
