Yes. Putting file server and DC on the same logical machine is inviting
trouble at best, and at <50 users, one moderately fast server has more
than enough resources to deal with client requests. Virtualization is
probably the more common form of deployment nowadays…

Fileserver storage will obviously vary, and RAM depending on how much of
said storage you want to keep cached. But neither server will need much
CPU power, and 1-2 GiB RAM will suffice for Samba alone (i.e., on the
file server you'll want a few gigabytes more for caching/buffering files).

No, about all virtualization solutions take care of that. DCs don't
generate much traffic anyway, so you'd mainly be concerned about making
sure there's enough bandwidth to handle the users' fileserver I/O.

For comparison, we have two servers with one Xeon E3-1230 V2 and 16GiB
RAM each per 10-person office in a master-slave setup with only one
active at a time, and the CPU load is negligible. At 50 users I'd only
be worried about the server's 1GBit NIC being a bottleneck.
