@steptoe I have seen builds of people having their outlets built into their machines but they never really show how it is really done which is what i would like to do with this as well but the thing is i need 2 USB ports on it as well for the Pi and for a 120mm fan i plan on installing and of course one of the plugs i would be using for the monitor.
The other thing is i need something like the first link you showed which i can never really find a proper tutorial on how to set that up cause that is something i plan on doing also.
Oh ya and also my build will be slightly different with the option of the arcade stick being pulled out from the machines because my stick i am still trying to build is a USB one and plan on putting a 4 USB hub in it so it would be easier to hook up other controllers/joysticks.
