Your motherboard doesn't have a video card slot.

Ouch - I had not noticed that. Whilst high-end graphics is not something I desire, I think I will be a bit frustrated by the on-board graphics. I'd like to have a DVI-D connection so I can use my monitor on that and my Sun workstation, which is only has an analogue video output.

This board has an AGP video card slot, and uses desktop memory
(unbuffered DDR, can use ECC unbuffered for error detection). The dimensions are 12"x9.6". About $175 USD.

Thanks.

The processors are 85 watts a piece. That is 16 amps for the two
processors. You might be able to run it with a 12V@24A output
power supply.

This PSU for $84 might do the job.

The memory doesn't have to be expensive, and if you want unbuffered
ECC instead of plain unbuffered, there would be a small percentage increase in price for that. The motherboard supports dual channel,
but you can even use a single stick of memory if you want.

I've managed to acquire 1 GB of buffered ECC for the Supermicro motherboard, but I guess that will not work in the Asus one.

I don't think your project has to be expensive. It would help
a lot, if the coolers and hardware fittings came with your
free processors.

I suspect they do. I am not sure, but they are upgrades for Compaq servers.

While a desktop case can probably hold that
motherboard, I don't know if there are mechanical details about
the cooling solution, that a desktop motherboard tray won't
support. I thought some Xeon coolers had some part that screwed
into the tray.

I should get the CPUs today, so will look. As far as I am aware, there is nothing like that.

I recommend having a look on http://forums.2cpu.com for more info
about PC-DL, and potential cooling solutions.

Cheers.

The Dell would be boring :-)

True. I'd really like a dual Opteron, but that is not so cheap. (Not helped the fact I am currently unemployed).
