 The Mellori ITX case was designed to fill the need for a small form factor case for AMD-based systems and measures
 just 195x190x60mm high (plus feet). The mellori achieves this small size by combining several existing innovations.
 First the AMD Raven Ridge CPUs have integrated graphics, allowing the system to omit a bulky graphics card to

 of the CPU cooling fan, that fan serves double duty. It cools all components while providing an aethetically pleasing feature
 on an otherwise non-descript small box. Air vents are on the bottom and force air past key components before exiting.

+Board Considerations
+--------------------

 The Mellori_ITX is motherboard-specific due to the location of the cooling fan cutout. This is easily modified by changing
 two dimmensions in the CAD files that specify the center of the cooling fan/heatsink relative to the back corner of the board.
 The original design was for the Gigabyte AB350N Gamng WiFi motherboard which also includes programmable LED lighting along
 the front of the board - Vents allow these lights to shine down on the desk in front of the computer.

 Mellori is designed for easy 3D printing. It is small enough to print on a 200x200mm bed and can be printed with almost no
 supports. Only the 4 small hex holes on the bottom need any support. The original version used thermal inserts for
 board mounting and the design can easily be modified if that's your preference.

 The back panel is a simple extrusion, so changing it for a different power connector or button is easily done
 using solvespace. The power connector cutout is for the 160W Pico-PSU from Minibox. The 120W Pico PSU is probably
 enough but it has a different connector. Feel free to experiment. The hole for a power button was designed to fit
