I always liked the idea of PC Engines small fanless computers/motherboards ... but one thing always bothered me - they were really pricey.
On the other hand - there are other multiple choices that serve similar role as PC Engines.
For example I recently switched to Dell Wyse 3030 LT boxes which are very cheap (20-30$ for used one) and they draw very little amount of power (3.8-4.2W measured with physical watt-o-meter).
