The HP Compaq dc5750 is a good choice if you want a business PC that won't grow legs. The HP Compaq dc5750 comes in either a microtower configuration or the desktop orientation that we tested. HP calls the latter model a "small form factor" system. It's moderately attractive, with horizontal black fins and some shiny black pieces.

The HP Compaq dc5750 uses small, traditional fans inside - one in the power supply, located against the back of the case, and one mounted on top of the CPU's heat sink. The HP Compaq dc5750 uses an air scoop to channel airflow over the heat sink.

The HP Compaq dc5750 is reasonably quiet, although noticeabbly louder than other PCs in the PC Advisor Test Centre.

The Athlon 64 X2 processor used in this PC can take advantage of AMD's Cool 'n' Quiet technology, which allows the HP Compaq dc5750 to adjust the speed and voltage to meet the user's needs. AMD says that Vista systems can take advantage of the technology without a driver, whereas XP systems require one.

The HP Compaq dc5750 has quick-release mechanisms for its optical drive, power supply, and expansion cards. But there are some glitches. The HP Compaq dc5750's expansion slot retainer is a metal piece that's held in place by the top of the case, for instance. Remove the top and the retainer can rattle around.

Our test HP Compaq dc5750 had integrated graphics, which we worried would slow Vista's Aero interface, especially because the system came with only 1GB of system RAM from which the graphics system could steal. But we ran Aero with no problems.

Even with integrated graphics, the HP Compaq dc5750 lets you connect two monitors simultaneously - one DVI and one VGA. The HP L2045w LCD monitor that shipped with our HP Compaq dc5750 allows height adjustments, swiveling and tilting.

In our WorldBench 6 Beta 2 real-world speed benchmarking tests, the HP Compaq dc5750 scored a 62. Compared with power Vista systems we've tested previously, the HP Compaq dc5750 is quite slow. If you want more power, you can opt for AMD processors with slightly faster clock speeds, or choose a slightly different system and configure it with an Intel Core 2 Duo processor.

The HP Compaq dc5750 did not have a chassis-intrusion-detection mechanism installed, but HP offers it as a no-cost option. You can buy a port guard to prevent unauthorised USB connections, and you can disable the front-mounted USB ports in the password-protected bios. HP offers a security sleeve for mounting the system under a desk or on a wall, but only for use with the desktop version.

You can use the Trusted Platform Module security chip embedded in the motherboards along with included software to encrypt passwords and document folders. The chip works with Vista's Bit Locker security feature, which lets you encrypt your entire hard drive.
