Several rack hardware manufacturers make shelves that have EIA spaced ears
on the front. It's just a single piece of sheet metal with 4 bends, and a
few punches. If you're getting more than a dozen or so, a local sheet
metal fabrication place could probably make a bunch for you, and put in all
the mounting holes you'll need for the mobo, etc.
Check the companies supplying stuff to the music industry. (I seem to
recall a company called Middle Atlantic Products that does all sorts of
these folded and punched things) In single unit quantities, they'll
probably be around $50-60...
