The first pic I'll give is going to be the timer relay circuit board, but won't have enough money to start everything for a couple more weeks :/.
Looking forward to seing your project. Just something to mention though. Home depot wire is for exactly that, the home. Try to find some good stranded tinned automotive wire. Will save you routing and other headaches in the long run. Just my .02c
I was saying stay with 8 gauge wire. If you plan to run amps and stuff then I recommend you go with 4 gauge. Unless you have a monster install and amps, you do not need 0 gauge.

I prefer to use the 2-4 guage welding cable for power. Only comes in black though so colored heatshrink is a must when doing power cables. Its double insulated and as flexible as a wet noodle. Also good marine grade tinned connectors crimped and soldered then heatshrink gives a very clean reliable install.
Wow. You folks are overkill on the wire gauge. 8ga for 3A? But I can understand it as a matter of preference.
I just looked at this project today. I was wondering what the purpose of the timed relay is. If you are using an automotive PSU for the computer, everything you need is there. I trigger my amp, power my USB hubs and monitor via a spare hard drive power connector. The PSU has the timing for startup and shutdown. And my generic PSU doesn't have an amp trigger on it.
I do like Hijack's idea of an extra switch in the mix to keep the PSU going while ignition is off. Just have to put a diode in so it doesn't backfeed into the car and keep everything else alive too. Or I guess a SPDT to toggle between always hot and the ignition switch would work. This will be added to the spring project list. It's just too darn cold to work outside too much right now.
I'll update this thread probably in a week. I've changed a couple of things and ordered all the parts/wires. This build is going to be upgraded slowly overtime and therefore I have to plan everything out, so it can be upgraded without changing parts. In other words I'd rather add parts then have to remove and add parts.
I got the timer relay finished it has like a 45 sec delay even that I only need like a second delay, but doesn't really matter I can adjust it later if needed. Later on not everything is going to be triggered by the psu and the 3 position switch turning from manual to auto would cause the power to everything to flicker, but with a timer relay it will not.
I dropped the usb hub and instead I'm going to run usb 2.0 extension cables. I will be starting off with 3 extension cables and adjust that as needed.
