BananaPI analogue?

Question

NAS

The situation is such that there is a home NAS created on the knee: a pair of HDD 2.5 and BANANA PI. The hard drives are connected via USB. Everything works great (more precisely, it worked), but it's time to put BANANA PI on the media center with XBMC on board, and a new board is needed for disks.
So:
- GigabitEthernet, only with a separate chip
- from 4x USB 2.0 or 3.0
- If there are a couple of SATA connectors, it's generally super.
- from 1 gigabyte of RAM
- support for Ubuntu or Debian. (access via SSH)
I would like a single-chip board, but are there any for a sane cost? Budget up to 8 thousand rubles. Unfortunately, for this money you can assemble a stove from C2D, since there is no longer enough for miniItx. And the performance of ARM systems, judging by the BPI, is enough for the eyes. What do you recommend to buy?
