So there's that, and this:

Today I stripped out the motherboard, removed the drive bays, all the front panel wiring, PSU, basically anything that might be in the way, and mounted the LED strips. I got the ones that will sit behind the mobo and the ones behind the front panel as well, but I need some 4-wire ribbon cable and probably an hour or two with the soldering iron to get them all wired up nice and proper.
Also the adhesive that came with the LEDs kinda sucks, so I'm going to look in to different double-sided tape, likely that really awesome 3M all-weather outdoor rated stuff, which I've used to stick badges back on to my car and have held for 4+ years of rain, dirt, sun, and wind. So I think they should hold some LED strips inside a computer just fine.
If anybody knows where to get a spool of four-wire ribbon cable (preferrably red/green/blue/black so I can keep everything color coded), I would be pretty grateful.
Mod on!
