Externalizing 600 Watts

[IngwiePhoenix]

I am working on a custom PC case, as I am trying to crunch a beefy PC inside a (rather roomy, if routed smartly...) Sony PSX DESR-7100 enclosure. The issue I am hitting right now is that I need a suitable power supply.

HDPLEX and PicoPSU don't deliver enough power for this... Any idea?
