I have been on a streak lately of modifying/tweaking this 5,1 to my liking. I added some 20cm LED strips and powered them off the lower SuperDrive SATA connector.
LEDs used:
2x Nanoxia CoolForce 20cm LED (one red, one white)
SATA to Molex 4-pin adapter:
Nippon Labs SATA to 4 pin
4-pin to 3-pin (fan connector):
Modtek 4-pin Molex to 4x 3-pin
One strip is placed adjacent to the GPU, and the other sits above the CPU tray. Please pardon the dust.

SATA to 4-pin in action. Getting the drive cage back in required unplugging this contraption and was a complete PITA.

3-pin power peeking through next to the front drive bay.
White LED strip mounted above the CPU tray area.

Finished product!
