I'm thinking about buying some 4 way connectors to allow myself to stack the 2 frames I have. It would be very simple to do, also doubling up on motherboards and PSUs for maximum hardware density is an idea im toying with.
Openrigs.com is legit and they created and shipped the items they said they would.
Overall they look like great finished products.
Verdict: Happy with them so far... I'll know more once I start adding components to them.
