About Us

Our story...

Ever since 2004, when I built my first PC, the case was the part I was always excited about the most. Sure, I have always tinkered the CPU's and GPU's, but the case was the part that always gave me that rush.

In late 2016, I have discovered the fantastic new world of SFF cases, and in 2017 I built my first PC in one. But, I wasn't satisfied with the layout and thermals, so naturally, I figured I can do better. And after a lot of 3D design, testing and prototypes, I was finally able to present the first version of the P-ATX case.

Based on P-ATX design philosophy, I will continue to develop other cases which will improve hardware compatibility even further, and thus have a line-up of cases with excellent space efficiency, for every hardware, and any purpose.

Case design journey

The first version of P-ATX was 9 liters in volume, but fit a lot of hardware!

After the first edition, small improvements were introduced to the V2 version:

  • Small increase in volume from 9 to 10 liters for better hardware compatibility (only 9 mm wider).

  • Improved construction and sturdiness, especially with side panels and stand.

  • Clean front panel with USB ports moved to left side and power button to bottom.

  • New finish - whole case is powdercoated in black or white with texture

  • Still the same excellent thermal performance, increased ventilation area on the right side so you can flip the PSU

  • Better quality GPU riser

  • Fits taller 2 slot and 3 slot GPUs, and longer GPUs with 120 mm AIO with included 92 mm fan adapter

  • increased CPU cooler clearance to 59 mm

  • easier to build in and to spec the build thanks to better compatibility

We are continuously working on improvements - do you have a suggestion? reach out to us at

Corporate social responsibility


We take great care in prioritizing sustainability and community welfare in how we operate within our company and in choosing our collaborators and suppliers.

Community welfare - Who do we collaborate with?

We collaborate with

  • Two highly specialized Croatian companies that cut and bend metal sheets that become your P-ATX and apply the powder-coating.

  • CZRR - Rijeka Rehabilitation Center that supplies us with 2 custom made boxes.The organization supports young people with disabilities and adults over the age of 21 with intellectual difficulties. We see the continuation of good cooperation as a priority and we believe that it will be continuous and long-lasting.

Sustainability - environment

Our operation produces a small amount of waste, of which all is recyclable as it is metal and plastic from the packaging.

We have specialized bins for recycling and we recycle 100% of the waste produced.

Our suppliers fully recycle scraps and recyclable waste produced during production.
