Dual motherboard cases

[Donald B. Kinghorn]

Hi all,

Do any of you know of any compact dual motherboard cases? [ by dual 
motherboard case I mean a case that will accommodate two full ATX 
motherboards] I'd like to build some 4 processor clusters (two dual processor 
motherboards) in a single case. I know of a couple of HUGE server cases like 
the one from Cal PC (which I've used) and Chenbro but I'd like to find 
something about the size of two standard mid tower cases. Preferably made of 
Aluminium ... nice anodized black  ... something like the Lian Li mid tower 
cases would be great :-) 

I've spent quite a bit of time searching on the web but haven't come up with 
anything acceptable. I'd consider custom fabrication but the cost needs to be 
under $700 US.

Anyone have any ideas?

Thanks
-Don
