http://www.starcase.com/DS_rack_pre_pack_kits.htm im looking for something like this. the 24U style. seems absurdly expensive. i cant imagine this would be too hard to build, but if anyone knows where to source one on the cheap, i'd be interested in that too.
This may be more of what you are looking for:

I have a raxess rack, and I love it.
A little different than what you linked but along the same vein and much less expensive

I bought one of their TV stands / eq racks and love it. Really nice construction, easy to put together and looks great.
This seems like a practical idea.
