Lian Li's Strimer turns your ATX cable into an animated rainbow (or your color of choice). It looks good an is easy to install, but we'd like an off button.

Depending on where you stand, RGB lighting is either a fun way to customize your PC, or an eye-searing scourge that’s infecting the previously dark and cozy corners of the computer world. Well, bad news for those who lean toward the latter: Lian Li’s $40 Strimer brings RGB to yet another area of your case- the previously rainbow-forsaken realm of the 24-pin ATX power cable.
