Bling Power Cables
I’ve never seen the point in adding internal lighting to your PC but if you’re that way inclined you can now do it really easily with the LED Flash Power Y Cable.
The LED Flash Power Y Cable acts as a two way adapter for the standard power connectors found inside your PC but all 3 ends also incorporate bright blue or red lights, making your PC internals glow. Probably not suited to the typical beige PC but if you have a flash case and want to make the most of that glass window then why not.
