Mac Mini “Rack Pro” Kit for M4 Mac mini and Accessories
Turn your Mac Mini into a securely-stacked rack of components
Yeah, you just knew I had to do it – turn my popular “Mac Mini Pro” enclosure into its real-life rack-mounted equivalent, with a fun twist – actual functionality!
This kit allows you to print a miniature rack system to use for a rack-mounted version of a “Mac Mini Pro”, together with many popular accessories that are similarly-sized. Each rack “1U” rack unit is 25mm high and 146mm wide between the rails – it turns out this is actually really useful for organizing a lot of gear in a clean, compact setup!
Compatible “Rack Mini” enclosures/rails are provided for:
- M4 Mac mini (3U) – with space to spare under the magnetically-attaching lid for a small SSD or 2
- Elgato StreamDeck Mk2 macropad (3U)
- Focusrite Scarlett Solo Gen4 audio interface (2U)
- CalDigit TS3 Plus Thunderbolt 3 Dock (2U)
- CalDigit TS4 Thunderbolt 4 Dock (2U)
- OWC 1M2 Thunderbolt 4 SSD Enclosure (two of them, side-by-side) or similar SSDs. (1U)
- Unifi USW Flex Mini 5-port gigabit managed switch
- CalDigit TB4 Element Hub Thunderbolt 4 hub
Let me know if you have requests for other hardware adapters, or feel free to post your own and link back to here for the “system”. Provided to aid in the design of other modules are STEP (modifiable CAD) files that are sized to be empty templates in 3 sizes:
- “1U” (25 mm)
- “2U” (50 mm)
- “3U” (75 mm)
Larger sizes can be adapted easily. Subtract from these templates the geometry of the hardware you want to mount, and either tailor the clearances to provide a snug fit or add another means of securing the device inside.
All of the equipment enclosures slide into the provided vertical rack rails and can be more-securely attached to the rack with an M3 flat-head cap screw through the vertical rail into a heat-set insert in the side of the module rail-slide. The rack itself can even be secured to the tabletop using the countersunk holes on the footer piece.
Printing guidance
Most of these items are easy to print with minimal supports, if any – even the rack-mount M4 Mac Mini Pro case. Use the recommended settings in the provided print profile.
Assembly guidance
Nothing major to note here. It should be reasonably self-evident where to put the M3 heat-set inserts and how things go together. I use M3 inserts 4mm long and FHCS M3x8.
The lid for the Mac Mini Pro rack enclosure is secured with four 10x3 refrigerator magnets. These can be pressed in, or, if too loose, secured with a dab of CA glue. Be careful of the polarity.
Usage guidance
Note: I recommend installing the M4 mini on the base of the rack unit with 1U to spare for cooling airflow. I would not recommend putting any equipment modules directly beneath the Mac mini – this will starve the intake and exhaust of open area for airflow to the thermal management system.
Previous updates:
12/28/2024 UPDATE:
Fixed TB4 Element Hub in response to feedback.
12/27/2024 UPDATE:
Added equipment module for CalDigit TB4 Element Hub as a user request, as a separate print profile. Beta release only – fit check pending requestor feedback.
12/25/2024 UPDATE:
New print profile providing several simple accessories for the rack system:
- 2U Keystone panel (7 jacks)
- 1U Cable Passthrough
- 1U Vented Shelf (remove modifier block to make solid)
- 1U Drawer
- 2U Drawer
- 3U Drawer
All of these easily print without supports on any printer.
In the next update I will provide a simple means to create a taller rack and to join multiple racks together.
