Hello, For school I am doing a Major Design Project on making a compact mini computer case, which can fit a Mini-ITX motherboard, and other standard computer parts. I would just like to know, what makes a computer case successful; aesthetically, functionally, and ergonomically? Ideas could be like: Magnetic dust filters, or thumb styled screws. All ideas will help. Thank you.
