I used old server rails when I built my drawers in 2011 and they've held up fine over many miles of dirt/rock roads.I'm curious if anyone has ever used old server rails instead of buying new drawer slides. The ones that come off of the storage arrays are really damned beefy.

At one point the mounting screws started to get loose, so I reinstalled them with some threadlock which fixed the issue. The "lock at full extensions" mechanism is wearing out a bit and if you bump the drawers they'll close, which can be a minor hassle if I park on a steep hill.
