Small Form Factor Computer Cases

When first exploring computers, the focus was on ATX motherboards, ATX power supplies, and large full-tower cases. This was my attempt at designing an affordable and still practical computer that would fit in my compact desk setup.

The construction of the case is all angled aluminum that is cut and bent to shape. There is one large continuous loop that is supported by more angled aluminum riveted together creating the case for the internal components. 

This design was for M-ATX motherboards, ATX power supplies, and space for any graphics cards. This allows for the components to be affordable and still be as compact as possible. 

Previous renditions were comprised of MakerBeams, 10mm x 10mm threaded aluminum extrusion, and accommodated two expansion slots with risers. What is a stand out feature for this case compared to modern cases of similar design, is all of the ports being accessible on one side of the computer. Cases such as the Meshilious S have vertical expansion slots that achieve the compact size but can put more strain on cables.

After all of these years, these designs still hold up to today's range of SFF case designs. While they need some refining these designs reached their target of being as compact as possible with unoptimized part choice and promote a well ventilated environment for computer components. Considerations I have from these older designs are dust filtration, external I/O, power button location, sfx power supply configurations, and size. The market for cases similar to these has vastly expanded over the past few years and while many are larger than these designs, they are also much more affordable with the added convenience of a warranty. 

Key Takeaways:

• Iterative design

• Comparing materials for affordability and ease of assembly
