I need a home server for running couple of services, since my current hardware is aging. For example:
- File-Server (SMB, AFP, FTP)
- CalDAV / CardDAV
- ownCloud, maybe WordPress
USB 3.0 is a requirement, since I want high I/O-Rates beyond 25MB/s, also access times should be fast (e.g. Hosting the library of a photo manager on the network share with lots of small file reads). The CPU/RAM should be juicy enough to carry out those requirements on the various file protocols, and to run the ownCloud PHP stuff smoothly.
I want to focus on low power consumption because of the 24/7 runtime. The number of hard drive bays doesn't really matter, I'm using USB-Drives so far and don't necessarily need to change this. Operating system will be some Linux, I don't want any custom/proprietary flavour e.g. Synology DSM, just plain Linux with full control. Display output won't be needed at all. No redundancy is needed as well, so one PSU and one gigabit Ethernet port should be enough.
What kind of hardware should I choose to get the most performance with least power consumption and lowest cost? I thought on ~400€ (~430$) max, don't know if that's possible. Of course it'd be nice if the requirements were possible at even less than 400€.
I'd prefer to buy the individual components and assemble the system myself, but I don't know if it gets cheaper with pre-built systems. Are there pre-built systems that meet my requirements? What hardware would you choose if you had to assemble a similar system?
