I can only speak from my experience: I did built a home-server with exactly your needs from an intel atom (N270 @1.6GHz 2GB-Ram). Hardware isn't that much more then the rasperry, it has real sata, real gigabit ethernet (*), something like 2-4GB RAM and a faster cpu at least with HT, nowadays even with dual-core. And power-usage is mostly dictated by your disks. I have a solid-state drive for the os and the logs and the incoming-folder of the torrent. Everything else is on one of two hdds which spin down when not in use (and when outside my home-office-hours). (*) actually it has two gigabits and 6 serial interfaces as its an industry-board which did cost something like 120€. It runs: - yate - firewall + squid + privoxy + several openvpn instances - mpd (music player daemon to have the same audio in all our flat) - backuppc - apache with php and python - mysql (for some small development projects) - postgresql (for some other projects and as backend for yate) - with its internal wifi-card (mini-pci-express) it also saves the access-point. - nfs server - sometimes test-setups of gluster/ceph/sheepdog When backuppc runs for two clients and a movie is decoding, music tends to stutter. But all in all I am very content with the performance of that baby. Have fun, Arnold
