Eventually, went to Storables to pick up shelving to put Vela on, and dropped by the office to pick up Vega's case.. Got the shelf put together, but when I went to assemble Vega, I discovered that the motherboard I'd bought takes a DC power input OR a two-pin input from the power supply. Sooo.. I ordered a new one. And new ram, because nothing that takes an ATX power connection takes SODIMMs, apparently. So, I've got a motherboard an ram I have no need of, and I can't return the motherboard, since I opened the box. Guess I'll have to find a use for it some day. Maybe buy a slim case and a power supply, low end cpu, use it for.... something.
Annoying, because this was the only dual-lan mini-itx motherboard I could find. Frustrating.
