Bruno started a thread over here in OT on just that subject. The Middle Atlantic box that loren pointed to looks peachy for Empegs.

A side note: I can't remember the name of the company, but at least 3-4 years ago Compaq rack-mount chassis were made by a company in Germany (I found this out the hard way when we tried to get seismic engineering specs for them for a project in California). They may have other stuff in their line that maps to what you need. If it'd help I could try to dig up their name.

[edit: IIRC, the name of the German company was Ratel, but I don't find anything under that name. Either my memory and/or spelling is bad, or they have changed names, gone out of business, been acquired, or .....]
