Home router with built-in hard drive

Question

WiFi

We are looking for a modern analogue of the ASUS WL-700gE router for the home.
Key points:

1. The hard drive must be in the same case as the router;
2. Gigabit ports;
3. 802.11n
4. USB port required
5. dd-wrt/openwrt support;
6. Or (what the hell is not joking) ARM processor to install a Debian lamp;

Nettop not to offer. It has a video card that the router does not need.

Answer 1

Why not take some good old wl-500w and a box with an external hard drive for it?
Only on the demand of gigabit does not pass.

Answer 2

Time Capsule.

Answer 4

I was given an ancient Buffalo's LinkStation (made in Japan!)
Only WiFi is missing from your list, but this is solved with a $15 USB dongle.
Well, the configuration is only through SSH.

Based on requests, only mini-ITX comes to mind ...
