Build Description

With the intent to bring my gaming PC with me to college (which is on the other side of the United States), I designed and built the smallest case that could feasibly fit all my existing components. This project is the culmination of 4 years of High school Engineering and Shop class and Robotics club, along with several months of in depth design and prototyping work.

This build required a significant amount of modding to most components in the PC. Of these include:
- Server power supply modded to be modular,
- Custom cooling solution for GPU (the RTX 2060 KO was modded to be single slot air-cooled)
- Custom cooling solution for CPU (using a server heatsink and salvaged projector fans)
- Using the fans as mounting for RGB LEDs
- Rewiring the front panel to work with MB

Despite its small size, it still packs a decent punch for gaming. The i5-9600k sustains approximately 4.6Ghz under load at 80C and the RTX 2060 KO runs at stock clocks while having lower than stock temps. On the topic of temps, this is one of the rare occasions where the build performs better with the side panel installed as the exhaust fans are perfectly positioned to pull air from the heatsinks. It also manages to fit in a 2.5" SSD mount in the front.

Now, when it comes to the actual portability of the PC. It'll fit in pretty much any bag, but actually carrying that bag around can be a challenge. It is one heavy PC given its size (heavier than some M-ATX builds that I've done). Running through DTW airport with it due to a tight connection was not a fun experience let's say.

Favorite Feature

The power button has a very satisfying press
