I still didn't move my main PC to a mini one because it's not that old and I don't feel like relegating it under a table, but migrating everything else to mini PCs (music, servers, firewalls, media players, ...) was the best choice ever; even the FreeBSD based NAS runs wonderfully on one of these small boxes. Unless one needs specific interfacing capabilities (GPIOs for instance) or serious performance which would need optimized airflow that only a bigger case could allow, the Mini PC form factor wins almost everywhere.

Great site, I'd love if it also took data from EU countries Ebay sites too, as buying from the US from here would inflate costs too much when adding overseas shipping and taxes.
