lots of storage
Quiet case and fans (no need to hear your PC in the middle of a movie)
Basic sound card, gives you optical out for running to a surround sound, you can drop it if you plan to use HDMI, some Blu-ray playback softwares will not do surround sound through HDMI unless you pay more, so it may be more economical to use the card
APU for integrated graphics and low price
8 gigs of ram
Aftermarket cooler, not for cooling purposes but for noise reduction
Added a card reader because it isn't really a media center if you cant easily load your videos/music
Wifi card included
