I. GOALS
I was searching for a good, small and cheap mATX case for my portable PC build. And...I didn't found case till now that accommodates all my needs. Goals of this case are:

III. STATUS & ACHIEVEMENTS
The Cube's frame and base plate are made of 2mm steel. Which should give good rigidness to all construction. Frames are the most complicated parts. It is really a challenge to manufacture them, so I made 3 models, which include bending and welding in different proportions.
Drive brackets have four mounting spots for 2.5" drivers. Most of case parts are made by simple cutting and involve no additional work. All external panels have dust filters. Case can be manually assembled and disassembled. Front and side panels are held by magnets, while other parts are assembled with screws and bolts. This fact allows to create DIY kits with volume much smaller than actual case and therefore have less shipment cost.
The Cube is one of few cases where motherboard lays flat, which gives less tension due to massive cooler or GPU. Case features 2 horizontal divisions: bottom for PSU and drive bracket, top for motherboard, GPU and CPU with it’s cooler.
Button division: PSU has it's own fresh air circulation (bottom -> back), drive bracket is cooled by 80mm fan with airflow back -> front. There is a big chunk of free space behind PSU which allows to use non-modular PSU and have good cable management. Length of PSU isn't strictly limited and limiter bracket can be removed.
Top division is divided into 2 chambers with GPU, so they both have separate airflow. GPU takes fresh air from left side and moves it through front and back panels. CPU chamber allows radiator with height ~140-145mm. Air is taken from back panel with 80mm fan.
This planning allows using of powerful CPU and GPU with barely no overheating.
IV. COMPROMISES
Such a small case of course has some compromises in design. First of all is absence of 3.5" and 5.25" mounting points. There might be space for 3.5" drive, but personally I find this form-factors outdated. We have to move to 2.5" and, of course, M2 form-factors. Next is lack of water cooling radiator. This might be improved, but water cooling is frequently overestimated and pricy comparing with air cooled radiators. Case has no separate I/O. All panels are clean and have only perforation on them. Only back panel has all connections on it, including power button.
I was searching for a good, small and cheap mATX case for my portable PC build. And...I didn't found case till now that accommodates all my needs. Goals of this case are:
- Smallest volume possible for mATX case;
- Simplicity and cheapness in manufacturing;
- Compatibility with standard parts;
- Durability and high mobility;
- Ability to use powerful CPU and GPU without overheating.
