Passively cooled PCs are an interesting niche, often associated with the need for silence. Be it audio recording or home theater appliances, some situations are just not well suited to having a whirring fan.

Recently announced is the fit-PC4 is a fanless system, fourth in its lineage. This time the system is using AMD for its CPU and GPU. Two models are available, separated into "Pro" and "Value". Its specifications are broken down into the table below.

Interestingly, the company considers these devices "ruggedized" as well as fanless. As such, they have a 5-year warranty. It seems to be quite the feature-packed device with two HDMI 1.4 outlets, two Gigabit Ethernet ports, and an available slot for a cellular modem. The Pro even has 802.11ac WiFi. I am not entirely sure the intended purpose of this device, but the company claims that the previous generation product was often purchased by video surveillance and digital signage customers. Interestingly, Windows 7 and Linux are the two choices for operating systems.

The fit-PC4 is available now in either a $299 (Value-Barebone) or $380 (Pro-Barebone) model.
