Customizable PC Case Starter Kit

Welcome to the DIY PC Case Starter Kit! 

I've designed and build this back in 2023 and decided to share it with you know. I always wanted to design my own pc case that I can adjust in size to my current needs. 

All parts are printed in PETG (red) or PLA (black)

Personalization

This is not supposed to be set&forget print. Feel free to personalize your build. add custom parts/mounts, you can use different materials for the tubes (e.g. copper) as long as they have the same dimension

You can design your own side panels, radiator mounts or integrate a headset mount. 

My personal highlight is the integrated power button which sits neatly in the corner joint.

• M4 screws
  • 40mm: 21pcs (clamping mechanism for corner joints)

All Parts red in the image are printed in PETG, all black parts are printed in PLA. This PC is running in this case for more than 1.5 years and nothing deformed or broke.

I currently chose the following dimensions for the frame tubes, adjust to your needs: 

43,5cm x 17,5cm x 42cm (LxWxH)

Assembly Tips

• For assembly make sure to print 7 of the regular corner joints and one of the power button versions
  • Add the cones to the corner joints using the M4x40 screws and start tightening them until the start to touch the joint.
  • then start assembling the tubes to layout the bottom rectangle and tighten the screws of the joints pulling in the cones to generate some clamping force
  • build the top rectangle and tighten the screws. 
  • add the tubes for the height to the bottom rectangle, then place the top rectangle from the previous step on top.
  • The covers of the corner joints are screwed in from “inside” the case using a M3x10 screws. (see pictures)
• you need at least 4 of the perpendicular joints to mount 2 of the 12mm tubes for the mainboard mounts
• depending on your mainboard size you need to print the according number of mainboard mounts
• if you want to include a 3.5"HDD theres a tray included
• Fan mount fits 120 or140mm fans with my width, dimensions 
• I used 2 motherboard standoffs to lift the mother a bit further from the rear tube. 
• Make sure to print and place the 4 PSU supports! The PSU mounting cover will not carry the wait on its own.
