if you feel this is a tired and worn-out question, then please just move along.
two systems on which i'm happily running openbsd on are: alix and mac mini. alix for firewalls/thin clients, and the mac mini can handle pretty much anything i throw at it. both are relatively cheap (new alix and used minis) and function well. in addition to firewalls/thin clients, my needs do not include anything high-performance or high-bandwidth - mostly infrastructure services such as dns/dhcp/web for small companies. so what i'm looking for is something small like (or smaller than) these two systems, and just as stable, while being cheaper. and i'm looking for recommendations, not just suggestions - if you haven't tried it and loved it, don't bother mentioning it. i'm hoping the raspberrypi will eventually be supported on openbsd (if the hardware proves to be stable, $35 sounds GREAT) but i don't have the skills to go there myself.
