Hey everyone,
I've been working on a design for a 6 GPU rig and wanted to share what I'm doing. First off, I know that there are some pretty good rigs out there already. I studied a lot of the open frame designs out there and I found little short comings here and there on the existing enclosures so these the design has been evolving, tweaking/improving various aspects, I'll share some of the details of this on a future post. Mostly designing my own since
The rig design is pretty straight forward based on extruded aluminum for a solid build with adjustable rails. The motherboard tray and fan brackets are currently laser cut and I do have a few parts I'm testing with 3d printing.
Dimensions of the 6 GPU rig is: 520mm x 350mm x 360mm (W x H x D)

http://vi2.com/assets/rig_wip_3_IMG_6212.JPGLearned a lot from the first real prototype. In particular, I can see some real issues with some of the existing rigs out there that have fixed rails especially for the GPU support. I had to adjust the back rail so that the GPUs would sit nicely on them w/o interfering with the risers.
The PSUs right now sit on the front rails and hang off in the back. Not really a problem yet, but I could add another rail there to support the PSUs. I'm also in the middle of looking into alternate PSU options for mining rigs so that may have a big impact on how I mount and handle PSUs.
The motherboard tray is really nice to have and I'm glad I decided to add that instead of mounting stand-offs directly to the rails. What I did notice was that there is a LOT of stress on the MBs when installing things like the ATX power connector so I think its good to secure the MB onto the tray with all the standoffs.
Right now I'm improving how the GFX cards sit on the rear rail so they don't move around so much. I've also got some MBs that can support more than 6 GPUs so I may start playing with larger rigs too.
Just wanted to share what I have so far and see if anyone has any feedback!
