Design and Features
The HP is encased in a black plastic chassis rather than the sleek aluminum found on the Apple iMac. Its 21.5-inch widescreen display has a 16:9 aspect ratio. The screen has tilt movement on a single-piece arm, just like on the iMac. The open design of the arm allows you to place the wireless keyboard under the screen for easy storage. This feature, in my opinion, should be mandatory in other all-in-one desktops, especially when users are space-constrained.

The back of the desktop has a set of business-friendly ports, including 5 USB 2.0 ports (out of seven total), PS/2 mouse and keyboard ports, Ethernet, audio, and a DisplayPort. The DisplayPort is useful for workers who need a multimonitor setup. On the side, there's the remaining two USB ports, a multiformat card reader (SD and Memory Stick - related formats), a four-pin FireWire port (for camcorders), and another set of audio ports. Since the system is business-oriented, the 6000 Pro comes with a lockable cover for the back I/O ports, which integrates with the built-in Kensington case lock on the back of the system. Though it's lockable and has a chassis intrusion sensor, the 6000 Pro is still easy to open up for service by your IT folks. Two of the back panels open up for access to the two memory slots, the 2.5-inch hard drive bay, and the optical drive bay. Most 6000 Pros can be configured to the needs of your business; my review unit had an Intel Core 2 Duo E7600 processor, 4GB of DDR3-SDRAM, a 320GB, 7,200-rpm hard drive, 802.11b/g/n Wi-Fi, and integrated Intel GMA 4500 graphics. The hard drive, processor, memory, and wireless networking are customizable.
