Design blog post

WARNING: this design has never actually been made/put together. However, all the designs were about to be sent out for fabrication, so it might only require minor tweaks.

Example minor tweak: a remaining open question is how exactly to connect the drive bays to the frame. The plan was to 3d print a nut that fit within the T-slots and then screw the drive bays into that. The nut has not been designed.

  • corsair_500R_drawings: a set of drawings/dimensions for the Corsair 500R 3 drive bay, produced while I was designing the case around this bay. Everything is provided as is and without warranty, but it's worth re-iterating for this: I bought and measure the bay, but the part may change, or I may have screwed up the measurements.

80/20 Dimensions/parts

The latest version uses 1 inch 80/20 struts as a frame. As planned, everything has end taps, so you can screw directly into the ends of the struts.

Strut dimensions:

  • 4x 284.2mm. Vertical struts.

  • 2x 339.2mm, access holes at 55.95, 109.45mm. Front-to-back strut, top.

  • 2x 339.2mm, access holes at 55.95, 109.45, 226.5mm. Front-to-back strut, bottom. The extra holes are to accomodate a bar to support the PSU.

  • 9x 160mm. Side-to-side struts, both for the external frame (4x) and internal supports for the PSU and drive bays (5x).

  • 8x corner brackets (McMaster-Carr, 80/20).

  • 10x internal connectors (80/20).

Where to get struts:

Other parts

  • Planned drive bay used Corsair 500R 3 drive bays, one mounted right side up, the other mounted upside down from the top.

  • Motherboard standoffs.

  • The usual 6-32 and M3 screws for computer parts, 1/4in-20 screws for the frame corner connectors.
