The Rear Panel kit for the rc2014 is and excellent addition to your DIY vintage computer, but I never really liked the two large openings in the back of the panel to access the modules. 

The Bump-Out-Boxes for the rc2014 solve this problem, adding 3 additional panel covers per box! You can install the Boxes without any modifications to the rear panel; instead, they clamp around the panel itself. 

Additional hardware:

• 10 M3 threaded inserts
• 6 M3x5 BHCS
• 4 M3x5 FHCS
