NAS for class of 20 connected via wifi

[pengyou]

I am beginning to think that my best/cheapest solution for this is to build a server with a router attached that will serve up to 20 wifi clients. I originally was going to buy a 4 port NAS (use 3 for hard drives and one for a bluray writer) but I have not found one yet that has the capabilities to serve 20+ people via wifi. Can I find NAS that will connect to wifi router?

It would be nice to have raid controllers to speed things up, but I can do without...still would be fun to learn about a new thing

If you have extra hardware laying around you may want to look into freenas. It's software raid but that's actually a good thing when it comes to trying being able to recover data.
