I see X thousand dollars in your post
For you SBS Essentials users, check out Multipoint Server 2011. Microsoft is advertising it as a school software solution even though it has great applicability to the business world. Many people agree. Mutlipoint Server 2011 is like Terminal Server except much easier to setup. It was designed to integrate with SBS Essentials so you'll see all the users and computers and whatnot. (Domain Join on the Premium Version). Interestingly, it also works as a local Terminal Services type setup. You can plug several monitors and keyboards into it and they all act as work stations. If you got one very powerful server, you could outfit an entire office with just peripherals/thin clients. Furthermore, it's compatible with thin clients (thin pcs) so you save on the client comps there too.
