Got my two! I actually their very first order from their website, #1001. Due to my customization, they had to make a special order. But none-the-less, they had it shipped within 3 business days of order!
Note: I had them make mine slightly wider for a tiny additional fee (costs more to ship in two boxes). I widened the main runners to 19.5" for the flexibility of accommodating two PSUs; whereas, Detritus' original instructions are only 18", which doesn't allow you to stack two PSUs next to each other (leaves like 0.01" of clearance for mobo and two PSUs - that's too tight).
Will be running to Home Depot to pick up some flat pieces and angle pieces for the custom PSU mounts. I didn't get the kits as I am not sure if I am using one or two PSUs yet.
The motherboard in the pic is an old EVGA X58 FTW3 I had laying around to test fit a full ATX mobo.
NOTE: I am only using USB-style risers so I don't care where the motherboard is (see my trust to see a reference link). Do note that if you plan on using ye-old ribbon cables, you will want to place the motherboard on the LEFT, and the psu(s) on the RIGHT. This allows the PCIe slots to be centered under all of your GPUs. The style in the photos below doesn't stretch far enough to reach the first couple of GPUs with ribbon cables. Again, I only use USB-style risers, which doesn't matter.
(the black anodizing matches my desk perfectly woot!)
Those are my dirty mits and dust on the tubes. For the most part, the black anodizing is flawlessly done. Sorry if it looks all beat up - I didn't clean it before the "flash" of the photo and didn't see it until it was uploaded.
Seven (7) GPUs can fit with room to spare in the 19.5" width version. THere's a solid inch at the end as you can see, so even the normal 18" version can fit 7 GPUs nicely (though you can only use a single PSU - maybe install 7x R9 270s).
