I just got two cases cool master scout and cool master HAF 912 ,I put board in scout and all white wires where G , works fine, on HAF 912 the reset sw and the power sw are color not white saying G . Is there a differance in switches on these cases????
Its just manufacturers differences, nothing to worry about.
some cases black is ground, some use white, prebuilts use whatever colour wire is near I think lol
power and resets are momentary switches so theres absolutely no danger in wiring them up 'wrong'
