This seems quite unlikely. What motherboard are you getting three 16x GPUs on? That alone with the associated sever processor would be more than a used 3090, before even buying the three 3060s. Give full BOM and costs.

I already had the PC. I just mean the extra purchase of the graphics cards.

The motherboard is an MSI Pro Z690-A.

The slots are physical x16. Electronically they are x16, x4, x1 which doesn't harm anything at all.
