IBM ThinkCentre A51P

IBM's A-series ThinkCentre desktops are targeted at small to medium-size businesses. (Corporations that need a stable, long-term configuration will be more interested in the M-series.) The true highlight of this machine is IBM's attention to quality in design. In front--directly below the CD-RW, DVD-ROM, and floppy drives--are easily accessible microphone and headphone jacks, along with two USB ports. The back of the case has the standard gamut of ports that are clearly marked and color-coded. IBM also boosts reliability with utilities such as Rescue and Recovery, which lets you restore a previous drive image; the Embedded Security Subsystem, for securing files and folders; and the System Migration Assistant, for setting up a user on a new computer.

The tool-less entry into the case is literally a snap, and you won't need tools to remove components, such as expansion cards or drives. Nicely designed buttons and levers allow for easy access to all internal parts. To access the hard drive bay, for example, we simply pulled a lever and swung the entire bay outward on a hinge. We did encounter one small problem when doing that: We ripped the power cord from the socket of the drive as the bay swung open. Luckily, we didn't do any damage, but users clearly need to be careful opening this bay. A slightly longer power cord could prevent such accidents.
