A SteamBox IS a PC, what makes it different is following guidelines to make sure it flawlessly run SteamOS and its games. but it can run Windows too in dual-boot, if users need it to play games they like and that for any reason weren't ported to SteamOS. Choosing the most expensive SteamBoxes isn't mandatory, but choosing an assembled PC or building one that follow SteamBox guidelines totally makes sense.
