@ADutchGamer - you read my mind.

Here is my modular cable design for ATX powering of gridseed miners.
...
You can see from the design that this setup allows for dual mode miners to run safely with only 3 plugs per PCIe and allows for expansion of up to 15 plugs for scrypt miners on a single PCIe connector from the PSU. It also works well for those with 10 units as it leaves a single plug free to power a 12V usb hub if needed.
I have pretty much finalized the design except for the actual lengths needed. I could really use some help on that from anyone who has these units.
I need to know approximately how long 5 units are end to end similar to how they would be in a spotswood case and also how far apart the individual plugs on the units are (pitch).I have been pointed to a manufacturing house and will be getting a quote in to them as soon as the BOM, final measurements and order tally are finished. Once that is done I should get the prototype for testing from them and have pricing for you guys. If you haven't already drop a message here or in PM about how many devices you will be powering so I can determine what size order to put in, thanks.
If you have any comments or questions please feel free.
Approx 12-inches from the PSU to the front miner.
