The chassis provides an open 5.25-inch drive bay and a pair of hard-drive bays for future expansion. The hard drives face outward, which would make accessing them rather simple--were everything not locked down by screws. Tool-free cases, however, are generally reserved for boutique vendors and for models higher up the desktop totem pole (particularly in the performance category), so that isn't too much of a disappointment.

On the rear are six more USB ports (for a total of ten). You'll also find PS/2 serial keyboard and mouse connectors, and a gigabit ethernet port; the graphics card, meanwhile, has DVI, HDMI, and VGA connectors. The machine also offers 802.11n Wi-Fi, courtesy of a PCIe card. The antenna's connectors are in an awkward spot: just below the graphics card, impeded by any monitor cables you'll attach. As a result, the antenna needs to poke out to the side of the system, as opposed to pointing straight up. It's just a quirk of the slot placement on the motherboard, though, and it won't affect functionality.
You don't get much in the way of printed documentation; once you've fired the machine up, however, Gateway's InfoCentre offers everything you'd find in a manual. The utility also handles software updates and presents tutorials and quick-start guides for using the PC. If you insert a memory card into the multiformat reader, pressing the Photo Frame button pulls up an image viewer for organizing and browsing your files.
