A cable to transfer electricity to PSU?

[woox]

I am working on a PC mod, and basically what I want to do is make my PSU external, and have all the connections converted to a say parallel port, and have the parallel port go from external PSU, to my PC, and plugs into a custom parallel port I would attach inside the PC which would then redistribute the wires properly to the mobo.

Is it possible/safe to do this with a serial/parallel cable? Is there a better/smaller cable I could possible use to conenct all those multiple cables in masse

(think of it like a a laptop charger)

safe, should be, as you're not messing with the high voltage parts of the psu, but the parallel ports may have a bit too much resistance...
