Single Board Computer

Which single board computer to select?

My first SoC board was pcduino. Since it was one of the first boards and I used it 24/7.
It gave me some experience and I really like that Allwinner SoC A10 with 1GB RAM and 2GB storage. What I wanted was SATA so I could use my mini PC also as media server that support DLNA.Now I wanted to buy a new one, but which one?
