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)
This is what I'll start offering for our 140mm billet fan grill designs, after the existing stock sells out.. ..this frame size is much more adaptable to different applications
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..
