Fair enough. It is a nice box, though, just that Boxes are easy.
Of course, for a setup like that, what you could do is get an old, shitty case from goodwill or the like, cut the backing plate for the motherboard out, Measure and mark it, drill it a little, drop a toothed washer in and then run some small bolts through to hold the backing plate in place securely. Get a plug cutter the right size for the hole, get some plugs from matching scrap wood, then just glue the plugs back in on top. As long as you're careful putting the plugs back in, should look pretty much like you'd never drilled it.
