Since the very start this design has been an experiment in compacting a full performance desktop gaming PC into the smallest possible volume. The end result is an enclosure 1 quarter the size of the smallest production case capable of similar performance.

the exfinium name
The exfinium name/brand was initially coined as a faux latin term meaning "beyond limits" or "outside the boundary". It turns out to be very appropriate for this project. You may notice from these pictures that the graphics card actually sits outside the box in this design. Originally this was a consequence of choosing to not let very long graphics cards constrain case dimensions and yet still provide support for very high end cards. A happy consequence of this design is that this one part, that draws more power and generates more heat than the rest of the parts combined, has been removed from internal thermal management concerns and is able to be cooled optimally in free ambient air. The card is able to perform at its best while remaining cool and quiet and contributes nothing to the internal case temperature. Even under full load the prototype remains mostly inaudible.
