Custom Portable Mac MIni

DIY “Mac mini Laptop” Build Log

I couldn’t find a laptop with the exact specs I wanted, so I’m building one—clamshell base with a hinged/strut-mounted portable OLED.

Core parts

  • Computer: M4 Mac mini
  • Pointing: Apple Magic Trackpad
  • Keyboard: Keychron K3 (low-profile)
  • Battery: PADJYYUSZ 150W pack (110V AC out)
  • Display: XBONFIRE Store 16″ 2880×1800 OLED (VESA mount)

Why this build

  • Desktop-class macOS with swappable compute (Mac mini)
  • 16″ OLED panel with VESA so I can tune height/angle
  • Real keyboard + large trackpad
  • Internal AC inverter so the mini/monitor use their stock power paths

Current status

  • I’ve made a rough cardboard mock to nail down ergonomics and component placement before committing to a real shell. It already helped pin palm-rest depth, cable routing, and the back “hump” volume for the mini + battery.

Target layout (top-down, back → front)

  • Back row: Mac mini + battery side-by-side under a vented cover
  • Middle: Keychron K3
  • Front/right: Magic Trackpad (large surface, centered to spacebar)

Working dimensions (approx)

  • Mac mini: 127 × 127 × 50 mm
  • K3: 306 × 116 × 22 mm (base height = keyboard + 2 mm ≈ 24 mm)
  • Trackpad: 160 × 114.9 × 10.9 mm
  • Battery: ~184 × 45 × 123 mm
  • Base footprint target (v1): ~363 W × 425 D × 24 H mm (width = panel width + 10 mm; depth = battery 184 + 5 + keyboard 116 + 5 + trackpad 114.9)

One of my design goals is to have a removable trackpad and keyboard, perhaps even BT TWS speakers. I also want to add high speed storage and USB ports on the sides. It’s gonna require a lot of 3d modeling.

Hell nah dude!! I was thinking of doing the exact same thing.

When the M4 mac mini came out, I compared prices of the mac mini to the macbook air. This idea came up my mind, why don’t I make my own setup with the mac mini and a keyboard and a screen inside a suitcase( for Portability). This would have been cheaper.

What you’re doing is impressive now I’m motivated to crack up a better version of my suitcase macbook.

thanks :slight_smile:
My 3d modeling skills are pretty weak so I contracted someone from Fiverr to 3d model the clamshell and hinge, then I’ll cnc mill for jnccnc. Hoping the costs are too crazy

Still working on this just going back and forth with a mechanical engineer on fiverr


I just got the design back, not happy but I’ll learn some on shape I support.

Started 3d printing the lower deck for test fit. I will have to 3d print all the parts and make adjustments to the step files. I already foresee cable routing issues.

Early prototype

when I am done printing all the parts for this revision, for the next revision I am sure to make it slightly more compact and round the edges.

This is hella cool, do you have a title for this version? Could maybe go for a cyborg look for the missing parts?

Its my first serious 3d printing personal project. Using it as an impetus to learn industrial design.
New Update


Next I will have to tackle the linkages and the display holder, need to figure out how to do heat set insert and I need to trim things down a little more so the KB and mouse sit flush.
