Enlight Case 7237 are the white wires + or -?

[austin316]

I think negative, but this could be a big mistake.

The hot side of the(twisted pair) wires from the case's front panel(IDE Activity, Power, Reset, etc) are colored, but not Black or White. The Black or White wire of these twisted pairs is indeed the Cold side, or return to ground.
