Home server on Atom D425, is it real?

Question

DLNA

There is a device that previously served as a DVR, but since the need for video surveillance has disappeared, and it is gathering dust without work, the idea arose to use it in a home network.
What will the collective mind advise? What OS and software to use? Maybe there are some articles, FAQs, etc.?
Needs:
Storage of backups of laptops
Torrent rocking chair
File storage with shared access
Additionally: (if the configuration allows)
DLNA
FTP
Media combine
We have:
Proc. intel Atom D425 1.8
RAM 2Gb
HDD 500Gb

Answer 1

Yes, really, with the exception of the item "Media combine"

Answer 2

An atom is just a processor =)
Here you also need to look at the chipset.
If you have Nvidia ION there, then a media combine will also work out of it. If not, then it won't work. And the rest will start on any basin.

Answer 3

According to your requirements, it should pull everything except video editing.
