This pic shows some nas-T
mobo LEDs that'll really screw up my lighting scheme. There's a tiny green surface-mount LED next to the
mobo power connector that comes on when the
PC is turned on; a red surface-mount LED (just under the edge of the PCI-e slot) that's always on unless the
PSU is switched off or unplugged; and the ugly green diagnostic LCD board. All of those gotta go, because it's all about paying attention to the details.
I simply covered each with pieces of black electrical tape.
