The ET 2400, like most of the all-in-one's from other manufacturers that aren't Apple, is a three-legged design. Sound is provided by a single speaker bar at the base of the unit with a webcam mounted at the top.The major difference between the ET2400 shown above and the ET2400 we were shipped is the stickers. If you love stickers, you'll love this thing.
Here is a close-up shot of the system's rear ports. From the left, there's power, RJ-45, HDMI, standard VGA, a cable port (optional on some models), a Kensington lock, and four USB ports. Note that the HDMI port on the system allows its display to be used as an alternate screen / secondary monitor for a laptop or even desktop system. This gives the 2400IGTS a bit of welcome additional flexibility.
Here we have the system's back, both at distance and up-close. The third leg (visible here), proved capable of supporting the system at multiple heights without feeling loose or overly stiff. In the right-hand image, one can see the ET2400's 4-in-1 card reader, twin USB 3.0 ports, and dual audio ports. RAM upgrades are accessed via the panel immediately above the system ports (visible in both photos).
