Pulled the trigger last night and ordered the ZBOX and the DCDC power supply. That ZBOX is difficult to find in-stock at the moment, but Google product finder to the rescue there. I had to go through some 5 stores to find a combination of in-stock and one that would accept a Canadian paypal account (delivery is to the US because none of them had sane Canadian shipping).

I'll pick up some RAM locally as it's cheaper, and I'll toss in one of the spare 2.5" drives I have here now. I should have this started within the next couple of weeks.
