OMG! SFF PCs R so small! This review from SFFTech gets deep into the AOpen EX855-II XC small form factor mobo and case. This PC uses a Pentium M processor and Centrino chipset, a combo once reserved solely for the laptop market.
Using Centrino in a desktop seems a little weird, but the boys at SFFTech say that the low power processor allows for fewer fans and less noise. Benchmark results were standard for what amounts to be a laptop in a bigger case but it seems that this tiny PC would fit quite nicely as a media center device.
