I have an Elbox A4000D Busboard with 2 Video slots that is designed for installing the A4000 motherboard in to tower. I don't have the tower case though. I have mocked up an A4000 setup on the bench with both a Picasso IV and CV64/SD along with a Toaster 4000 in the other video slot and the system was stable for a 24 hour burn in.
I imported it from the UK to the US for a tower project but have since purchased a Quikpak A4000T so I no longer need it.
PM me for details if you are interested. I'll make a fair deal to recover what I paid for it, but I won't give it away:-)
Here is a link to a picture of one just like it.
