WiebeTech"s TrayFree bays are a breeze to add a drive to. It really is as easy as opening the door, sliding the drive in, and closing the door. No screws, no trays, it just works. The RTX bays are more rugged than ever. Featuring a blue/red power/access LED, and based off of the same TrayFree design as before, hardened bays sport 100% metal parts.
