If I were you, I'd plan for how are you going to remove the heat from the room.

If is one thing to blow a fan on your cards to move air, but when the room gets warmer
the whole cooling setup becomes less effective as ambient temperature raises.

Hint: Don't think A/C is a good idea. You don't want to use energy to heat air and use energy to cool air.

I asked that in the OP. So you're saying I should use something like liquid cooling?
I live in Los Angeles, so I can't just blow in cool air from outside.

Water cooling is expensive. If you are willing to spend $$$, go for it. You have to worry about pump failures, RT monitoring of pressures etc.
Lots of headache, if you ask me.

Better to position the shelf in the coldest room in your house (lots of ground/soil as heat sink) and run duct vents to the outside.
Ideal, natural setup would be a vegetables cellar, like they used to do in the old days. If you have access to a backhoe....

I think GPU mining is very inefficient way to mine. FPGA is much better. But if you have your mind set on GPUs, design your setup to
remove the heat. If you put multiple rigs each consuming 800W, you can add up all the wattage and that will be your heat that you have to worry about.
Not to mention the wiring. You can probably run 2 rigs on your 15A circuit, with three, you'll be tripping the breaker.

If I were you, I would stay away from GPUs, unless of course you already invested in the hardware.

What are FPGAs? I've heard of them but never known what they do
