Absolutely worked for me. I bought a used Mac Mini Server from someone upgrading to the latest and greatest, and got it at a great discount, maxed memory and loaded with software (including Win 7). The Mac Mini works with your keyboard, monitor, and mouse; although I prefer my bluetooth trackpad. For me, Samsung monitors and sound bar are a perfect match. I had tried some other non-Apple monitors which were difficult but Samsung monitors work out of the box.
My 2007 Mac Mini was reassigned to set-top box duty when I got my iMac. Its a great machine for that purpose, especially since I upgraded the processor from a Core Duo to a Core2 (which I wouldn’t recommend as a DIY project unless you know what you’re doing well enough to ignore my recommendation). Most of the time it runs headless, and I control it via screen sharing from the iMac or an iOS app.
