The packing material is nowhere near as polished as Apple's, but it's also no worse than that of a typical small desktop vendor.
The accessories include manuals and software for the motherboard and graphics card, as well as a handful of video output and IDE cables. No mouse or keyboard.
The front panel has two 5.25-inch bays, and one 3.5-inch bay. Our review unit came with a single DVD burner.
The Open Computer has two audio ports and a pair of USB 2.0 ports on the lower half of front panel. It doesn't have a media card reader.
The decidedly PC-looking back panel has a typical array of ports. It doesn't have eSATA or FireWire.
Inside it looks like any other low-end midtower desktop. You can add a hard drive or two, as well as a few more expansion cards. However, you only get two RAM slots and both of ours were filled.
