I've got a pair of the 4 inch cathodes, sleeved in my fave...black w/ red tracer in my newer build, looks to me like they've stepped up the quality of their sleeving a bit since the last time I ordered from them (a few months ago)
Corsair's H50 cpu cooler isn't escaping modification either... so how about a Billet cap?... I also painted the frame of the radiator Aluminum Silver... I'll be painting the cylindrical housing as well.. I'm pondering ideas for covering the Black hoses..
