Pulled from my recent system, was running EK-Cryofuel Clear. Cosmetic marks near the fittings, and the top of the tank.I was intending to use this in my next system, and so it has been through an ultrasonic cleaner with Dawn & distilled, then and then cycled through with fresh cycles of a distilled water loop for an hour each.Selling these radiators as a 3-pack, not interested in splitting them up.No screws or fittings are included with these. They take M4 x 30mm screws which can be easily found.
