Yeah, whoops. There're... several reasons that won't work. Decisions, decisions.
(I suspect the motherboard is probably the thing that's broken. Do I pick up the exact same one for ~$600? Do I write it all off (and sell off some parts) and get a new server? Do I try to find an old server that's compatible with the scads of RAM I have (and ideally, the processors too)? Marginal complication is that it's an AMD build, which isn't super popular in servers.)
