I've migrated most of the electronics from around my house to one central mothership cabinet. Right now in my cabinet I have two full power strips to accommodate all the wall warts for all of this crap:
HDMI splitter
Router
Cable Modem
DVD Player
Karakoe Box
Laptop
NAS
USB hub
POE Ethernet Switch
IP Camera
USB over IP Device Server
Projector
DVR
I'm thinking of adding a couple of more gadgets to the mix:
IR Blaster
Raspberry Pi
Printer
It already looks like a mess, and adding a 3rd power strip would put it over the top. All of these devices operate on 12VDC or 5VDC. I'm wondering if I am likely to encounter any problems if I were to chop off all the wall warts and power everything from one or more large ATX power supply(s). I'm concerned about making supply voltage common to devices that communicate with each other. For example, with the HDMI splitter, DVR, and Projector all being powered from the same supply; in the absence of the isolation provided by the host of wall warts, is there a chance that the Splitter, DVR, or Projector shorting one another out through the HDMI cables?
Is there increased chance of noise?
What issues could I face in doing this?
