There is max 4 users in a small business office that would be using the NAS. The main purpose is a file server for quickbooks and other applications. The quickbooks file will be hosted from the NAS. The other basic office applications would be stored on nas by individual pc's. Pc's are running windows as well. Looking for suggestions on a NAS either homebuilt or prebuilt. If prebuilt is around the same price its probably the better route.
