MK735 - The first 100% 3D printable Mini Server/NAS chassis in its class that’s truly printable, has been printed, has been assembled, has been beta tested by an international team and even modified by others. Somewhat time consuming but simple to print and assemble. It is designed to maximize airflow; keeping the system components, disk drives and chassis cool.

Printed the main body, and mesh filters in Prusament PETG, the door frame, hinges, and top cover in Prusament PLA. Great project and I would highly recommend it to anyone wanting to build their own home server or nas. There are only two draw backs to this case. First you can not use full size video cards so if you wanted to build a Plex server or run a steam game server you should look at the half height video cards that are no longer than 6 1/4 inches and verify if they can accomplish whatever you plan to do. Lastly CPU air coolers can take up a good bit of space. This case can not work with air coolers taller than 75mm and with no place for a radiator that can dramatically limit your cooling options and possibly your CPU selection. I am able to run a ryzen 2600 with no issues in this chassis with the standard CPU cooler. Absolutely love this case and can not wait to add more hard drives to it.
