I've got to figure out how to build my own 22u rackmount by the weekend, although I've never built one before. I recall a good tutorial on DIY racks somewhere on the interweb, but I believe that site's down now and I can't seem to find any mirrors of the original content. Did find this though:

This looks to be about the right dimensions, but I'll have to compare with industry specs. I've got to fit roughly 8us of server in there for starters (4u compaq 5500, 3 1u systems + 1u KVM). Looks like I'll be raiding the local hardware store tomorrow.

Speaking of compaq 5500s - it would be nice if an insight-manager work-alike could be ported over to BSD. If nothing but for the ability to quiet those silly fans down. It's hard to get decent use out of a server you can only run a couple hours at a time - the noise is enough to make talking on the phone difficult, not to mention the ugly looks as neither the cats or the wife appreciate the noise pollution.
