Can you tell me a budget and compact DLNA server / set-top box?

Question

DLNA

Good afternoon!
In my room, in the middle of an empty wall, there is a TV, into which various cables come, including the network. Until recently, an expensive Samsung SBB-c nettop ( https://displaysolutions.samsung.com/digital-signa... ) was lying on a shelf in my pantry.

Network balls were spinning on it via SMB, torrent, DLNA. You put a torrent file from your computer to a network folder, it is automatically downloaded and after a while it is available on the TV set via DLNA. My stupid SMART TV does not know how to use other protocols. The other day, the nettop went into the world of eternal hunting, now I am looking for a replacement for it.

Could you tell me an INEXPENSIVE and COMPACT solution that can do all the same functions? In terms of dimensions, I would like to get something like this:

The most important requirement is that the player should not be connected to the TV set directly via HDMI, only via the network, only DLNA!
If it will also be possible to insert a full-size HDD 3.5 into it, then there will be no limit to my joy.
OS - does not play a special role, Windows, android, linux, fryaha - everything will do.

If the Internet is via ethernet, then sell your router, buy a
Zyxel Keenetic with a USB 3.0 port + portable HDD 2.5 \ 3.5 with USB 3.0.
Or, as already advised - any minicomp
