Well it seems as though the original source has vanished. Sorry about that. It was basically a description of how to use an inexpensive board, SSD, and risers to run 6 AMD R9390 GPU's as one mining rig.

Sounds like good reading matter, if you come across a working link for it please let me know.
I have no idea why but I'm not getting notifications of your replies, will have to keep checking my reply tab more often me thinks :)

reply notifications have been buggy since HF19, I just look for new replies every 15 minutes or so of my "active" day

It isn't quite the same thing, but someone created a pretty good rig setup tutorial here:

I, personally, would bump the PSU to 1600w and favor an AMD Ryzen setup; using the parts in my wishlist;

But everyone has a personal preference ...
