you'll need more than a keyboard, monitor and mouse - each workstation would need at least a 'thin client' meaning a cpu with ram and a network card.
Some people do this in conjunction with a central server - all permanent storage is on the server, but this situation is still quite rare.
More common is to give everyone low-end PC's with their own permanent storage, but have all user documents stored on a central (higher-end, backed-up) file server. The advantage of this setup is that these kinds of pc's are easy to buy, and you get the added benefit of secure centralized backup.
