I'm building a webserver and need a tower that will fit in 4U of rack space. Thus, the tower should be no more than 18" in height, and approximately 5" in width (there's no limit on depth). Since I'm building a dual-cpu server, I'll also need a case that support e-ATX (12"x13" motherboard), and everything I've found so far is like 20" in height and 8" in width.
Are there any sites where I can specify the dimensions I want and turn up results that only fit those criteria? Or if you know of a case that'd fit that, that'll be good too.
I'm trying to avoid having to build a rackmount server. I'd rather build something I'm comfortable with.
Thanks!
