It depends on what you want to do with a home server. Is it a home entertainment system with ready-to-use entertainment UI? A computer in a compact case no larger than the size of a modem/router with just an OS installed (Linux, Windows, Mac OSX)? The former is popularly taken over by the integrated system within TV / media player (yes, many of the newest DVD & BlueRay media players do come with a better, surprisingly [1], integrated system), and you can play media like Netflix / YouTube from your mobile phone. The latter is somewhat a customized solution, depending on what you do. I would run on my old laptop, or I can run on a raspberry Pi (which is capable of running HD video at 1080p), plus a large SSD network storage device (or use "cloud" if you have a good Internet connectivity). There are plenty options out there, but for a $60 deal (USD) is pretty good. Most big brands can easily cost you $100+ with just Atom CPU in it. I wouldn't mind getting one though, if it becomes available again. [1]: Samsung BD-JM57C Streaming Blu-ray Player (love it)
