Power multiple devices from one connection

Hi everyone, I'm not an electrical engineer so I just wanted to ask a basic question for a home project I have. I'm trying to make a multi room audio system and I'd like to get it all into one set top box or PC case, My plan is to get 4 ta2020 amplifier boards, 4 raspberry pis and a 5 port switch and then put it all together in one case with a single power supply. First of all is this possible, and if so is there a company that can make the circuit that I need?

Hi,

What you'll be looking for is 12V for the 2020 amps, 5V for the RP, and the little switch I looked at also took 12V.

Computer power supplies put out those voltages and more than enough power for everything.

Youtube has many how to videos on modifying computer power supplies to make them useful for projects instead of powering computers.

You could also fill the computer case with a power strip surge protector and plug in a 12V/5V supply for each thing, but that would be a little crazy.
