For the longest time I've wanted to rackmount my computing setup. The problem is, racks are expensive as hell, and the only ones I can find are huge- over 20U. I was wondering, does anyone know of any place to possibly get a rack under 20U (16U or so would be great) for under $100? Or, how hard is it to build a rack? I have pretty much no skill when it comes to constructing things.
