Appreciate any suggestions you could make.
HDMI is a pretty common features on cards in every price range now but they are not universal. Providing them is often optional in the reference card designs so you just have to look around and see which have them and which don't. Most online shopping sites like Newegg should allow you to use that as a search criteria to speed things up.
It's entirely up to you but I would offer yo change the config to something Core2Duo or higher. Imagine time saving alone. Depending on the country you could sell your rig for ~€150. Add another ~€150 and you could get budget Sandybridge setup with small SSD. Enough for movie playing and even light encoding. Check my cheapo setup boot time for comparison: http://www.youtube.com/watch?v=fcY0bMp0r3w
