The Pure chassis is 3L. It is impossible to get smaller than 3.2L while using a dual slot gpu and itx motherboard. This is just due to size of components
It's quite hard for me to design a sandwich style case. I'm big on the details. For example, the screws on the ZS or K39 lack symmetry and their closeness throws off the design. I prefer a screwless front panel.
Custommod and other designs are very functional and probably fairly easy to produce. It is just my standards are design and quality is a bit higher. The K39 example I have skimps out on painting the interior parts.
Other ideas I have:
- Pure X2, supports external gpu that you can disconnect.
- Pure Slim 4L slim line version with gpu support.
- 5L 400W internal gpu chassis, with modular side panels
