Can't tell you the specs or price on this thing, but I can show you the back of the Inspiron Zino HD, which should tell you almost everything you want to know about it.
Now, I doubt it'd have an HDMI port and be called the Zino HD if it didn't output HD video. It's a little bit taller than the Mac Mini, but not by much. Not too shabby at all.
