The rear panel sports six more USB 3.0 ports, VGA and DVI out for the Core i7-4770K's integrated graphics processor (plus DVI, HDMI, and DisplayPort outputs on the discrete video card), eSATA, gigabit Ethernet ports, six optical jacks for various flavors of audio input/output, and a pair of antennas for the onboard wireless 802.11b/g/n Wi-Fi adapter. And of course, you can't forget about the GTX 680's HDMI and DVI ports.
You won't get a lot of gonzo features on the Flex 47B. There's no plastic tubing filled with exotic coolants coursing over the components, for instance, and there's no custom paint job. What you do get is quietly phenomenal performance for a very reasonable price tag.
