The Osmi case has been out for many years now. It was one of the original high end ITX PC cases to hit the market. The latest 3.1 revision from Spartex comes with some significant upgrades, most notably the fan has been moved from the top of the case, to the bottom.

Osmi 3.1 ITX CaseFrom $199.00

Moving the fan represents a major shift in the case layout and its cooling potential. Instead of having an exhaust at the top, and your GPU functioning as an exhaust creating negative pressure. The new layout pulls cool air into the case and directly onto your GPU. This new setup offers better cooling, along with the potential to do builds with a GPU de-shroud.

Osmi 3.1 Temperatures

Temperatures for this case were interesting. I found them to be manageable in my mid range gaming setup. Judging by the temperatures this isn’t the case for people seeking ultra high end gaming builds. This case would be great fora portable PC, or living room casual gaming machine.
