If you wanted to set up a server then I would recommend using it for all your shared stuff like art files as well.

For sharing a couple of docs on a closed network just pick any one of the machines you already have, Mac or Windows, makes no difference. Put the files in a folder on the desktop and turn on personal file sharing. You can set the share point to the specific folder so when you access it you are right there and no additional navigation is required.

The overhead of running personal file sharing for small docs is insignificant. A dedicated server is overkill unless you want to go thru the exercise of setting up a centralized business process.

Personally I'd set it up on the Mac but that's me.

If the info is just a couple of spreadsheets and not proprietary you could even set them up on google docs.
