The great appliance hunt.
AFAICT there is a (large) hole in the market re the availability of appliances for hobby networking. Specifically networking that requires storage such as file serving, proxying, even mail. I have been looking for a couple of years and still can't find someone to send my money to.
Some sectors seem to be covered quite well. For instance, the wireless router choices are reasonable, Soekris and PC Engines.
It seems that anyone wanting HDD storage with simple, low power boards has few options.
Please let me know your suggestions. I want to use OpenBSD for NAS (SATA) and Firewalling (two ethernet).
