What I'd like to do as I move forward, instead of buying lots and lots of PC based Power Supplies, I'd like to buy larger power supplies (maybe units that can provide 5,000 watts of 12 volts - or something...) and connect multiple miners to one larger PSU. Except, I have little to no knowledge / experience with large Power Supplies.
5000w of 12v? Even if you can do that, are you sure you can cool 5kw in a small area? A lot of home miners have to spread their miners around the home to avoid turning one room into an EasyBake oven.
5000w on 12v? Thats 416Amps! What kind of wires required for that PSU? finger thick? Is there a real one? Would like to have a look.
Also even if there's one, it may not be home friendly. It should require re-wiring as most of the 230v cables and sockets are only 16A max rated. So max you can draw from a power socket is 16*230 = 3700W
