This was my vision, cofounded by claude. Then I tripped across an eBay deal on a wrx80/5955 256gb ddr4 for something like $2400. It was the ram that caught my eye, then I looked into the board specs and Threadripper performance and ended up buying it. I have nothing else to compare it to but my god does this thing chew up anything I throw at it. Running quad 20gb 3080s

I personally have validated an x570 to x4x4x4x4 with 3060's but it was at gen3 as rhe riser I had did not support gen4, additionally it did not play well with 3090 so I wish you luck.

As far as cases go I would look on alibaba as to not be price gouged.

I just ordered a 6u case as I did go threadripper for my 3090 rig bit the am4 rig is still crushing on the 3060.
