DIY - 12U Rack Cabinet

 Back to Category:DIY

Introduction

In May of 2018 I built a 14U wooden rack frame, while working fine it was a very rudimentary build with no flair, heck not even rails (equipment was fastened directly to the wood).

In the beginning of 2020 as nothing more than wishful thinking, I began designing a rack cabinet in SketchUp. Beginning as a 24U cabinet (2 revisions), shifting to a 20U cabinet (3 revisions), then 12U cabinet (3 revisions), then dual 12U desk (2 revisions) and finally settling back on 12U rack cabinet (4 more revisions). Based on the EIA/ECA-310-E specification, I started with the Z-Series rails from Star Case and included all the features I wanted in a cabinet.

Build Pictures

I attempted to document the process as best as I could. The frame was made from the 2x4s once they were transformed into 1.5x3s, the bottom mini-frame is supported by oak 2x1s that I cut from a piece of oak (1x5) in my scrap bin. I then wrapped the frame in 1/2" sanded plywood, using hardwood dowels to secure the rear frame (making it removable).
