I am looking to build a custom server for storage and media centre.

- Processor is not that important since only sharing is going to be main priority.
- Need to have a quality motherboard. It should be able to handle big hdd capacity. And needs to have many USB3.0 ports (atleast 4).
- Network port should be good. If motherboard port is average, maybe a pci network card?
- Onboard graphic card is sufficient.
- No need of monitor or anything else.

What kind of price am I expecting?
