    Hi. I'm building some sort of linux system for digital video recording, mp3 playing and such (dont know yet exactly..:)

    I'm building the system on Asrock K7S41GX motherboard (mATX) which I'm going to install in some small case, which at this point is my old VCR's case. For PSU I have small Dell's power supply (from some pentium III system) which needed to have its wires reconnected to fullfill ATX requirements (Dell uses different wiring even though it uses normal ATX connector).

    I noticed Dell PSU didn't have -5 volt line at all but there's pin for it in regular ATX connector. Is -5V line needed these days anymore, or is it just some old relic? The system seems to work fine without it.
