Is this configuration tolerable for eth mining?

Question

Computers

There are 3 cards 2 X MSI GeForce RTX 3090 VENTUS 3X & 1 X EVGA RTX 3090, please take a look at the config I plan to build:
Motherboard: ASUS ROG STRIX X570-F GAMING
CPU: AMD Ryzen 5 1600 OEM
PSU: 700W SeaSonic SSR-700TL
RAM : 16Gb DDR4 2400MHz Corsair Vengeance LPX (CMK16GX4M1A2400C16)
GPU: 2 X MSI GeForce RTX 3090 VENTUS 3X & 1 X EVGA RTX 3090
SSD: 1Tb Samsung 860 EVO (MZ-N6E1T0BW)
Frame: Undecided
Will this all work? enough power supply? how to choose a case? you can’t put it in a regular case, I suppose?

The body needs some kind of shape. It can even be made from wood.

The motherboard from the gaming series is useless here.

Answer 2

4 GB of memory will suffice.
Screw in general, you can take any BU there is enough 200 GB
But the power supply is probably not enough. I think 800 or maybe 850 will be enough and this is provided that it is no worse than Bronze.
