my dad always told me, if it's to good to be true, it probably is.
most 6 gpu rigs will set you back about 2000 usd.
and they are selling a 8 rig for the price of what you normally build a 6 gpu rig?
with integrated switch, and rack chassis.
for all that the price should be closer to 3000 usd
for me this sounds like a scam,
I'm happy to test one, if they want and give a review.
