I used my pool hit to buy the four card and to get some more miner dude cases

I now have 4 filled with 8 cards each and will be getting 2 more cases.
I have a long relationship with that seller so he is discounting them to me.
I will fill the next two cases with nvidia rtx a4000
and the amd build.
I obviously will need other amd cards to fill the 12 card case. as 2x 6700 1 x 6600 1x w6600 will not fill the case.
Now that is very posh but the thing does cost the price of 64Mhs tho very nice if you have racks of them.
we go back a long way and I got a very good discount for the six.
but you are right they are not cheap.
very well made can do 120 or 240 volt.
they will lower my smos bill as I will merge a few small rigs into them.
I will end up with six doing over 3.9gh
I think the farm will be close to 6gh eth
and 33.5gh ltc/doge
and 2ph btc
