I just ordered a case for my soon to come Epia PC, an
Antec Minuet, but with an 220W power supply, not the 300W and I even think of replacing this one with a smaller one

Now I still need the Epia LT board, which noone seems to have in stock until now
plus hdd and ram.
You may ask "why this big case for a small epia board???"
Simple answer: I wanted a case, where I can mount an standard DVD drive, at least one hard disk and a card reader in the front. All of this fits on the Minuet case and I got it for 54 € including shipping (normal price is 80 € without shipping)! 
I think till I get the Epia, I'll mount my Sempron 2400 in there for testing 
ah, before I forget: YES, dual screen is supported for the CX700 chipset, drivers are available at Via! Though it seems like a big mess (new kernel, new MESA and so on), I'll give it a try.
