There are other small compact home servers on the market. One which I also own is a TonidoPlug, a "cloud computer" in the true sense of the word. It comes with a dozen buikt in apps and is the size of a package of cigarettes, plugs directly into a wall outlet with no power cord, runs a 1.2Ghz processor, 512Mb ram on a Linux Ubuntu OS. It has only a usb connection for your drives and a cat5 connector.
Take your smart phone and upload, download, serve the world anything, comes with Money, Thots, Jukebox, and about nine other apps. It has a built in email server, samba and ftp server. In a nutshell it does everything for you while on the go. It draws about 9 watts of power, equivelent to a night light and costs less than $15/yr to run 24/7. No more is the need to leave your computer on while on the go as TonidoPlug handles all apps as well as printing tasks.
Download Torrents with your phone and upload to Tonido and when you get home, its all waiting for you. CodeLathe, the makers of TonidoPlug is the only established manufacturer of cloud computers with built in apps. Buy another brand, program it yourself from scratch with Linux apps.
You also get your own domain name and SSL encrypted communications with a security certificate..........All this only $99........Unbelieveable.
