Next up is the desktop case. For the first time, we leave behind the notebook-style optical drives in favour of a standard unit. There’s also a 3.5in bay for a floppy drive. Two of the four DIMM memory sockets are unobstructed, although you must unclip the optical drive to expose the other two.

We also see two SATA ports on the motherboard for the first time, but that’s for taking a ghost image of the primary disk. For permanent dual-drive setups, Dell recommends the larger MT chassis.

The CPU and heatsink arrangement at the front of the motherboard is similar to the SF chassis, although with the hard disk beside it and out of the way the airflow to the rear grille is unobstructed, unless you run full-height expansion cards. There’s one PCI Express 16x slot and two standard PCI slots, all taking half-height cards. However, you can install one of two optional full-height risers, the first supporting two PCI cards and the second supporting one PCI card and one PCI Express 16x graphics card. Our machine came with a small DVI converter card in the PCI Express slot to supplement the VGA output on the rear panel.

GX620 SERIES OVERVIEW

One size fits all isn’t a mantra an IT department can live by. Different sections within your organisation, even different individuals, have their own requirements when it comes to PCs, yet choosing several different models rapidly increases support costs.

Until now, it hasn’t been possible to satisfy an entire organisation’s needs with one hard-disk image, but thanks to Intel’s 945 chipset that’s all about to change. Dell is the first manufacturer to rise to the challenge, with its OptiPlex GX620 range designed to satisfy diversity by offering different chassis and specifications, but with a common architecture and hard-disk image that will work across all models.

Here we review the entire GX620 series, so you can see how they stack up against each other. We also mention the OptiPlex GX520 range. No samples were available for review, but it forms part of the same family and the two ranges have many similarities.

In fact, the three cases that make up the GX520 range – Small Form Factor (SF), Desktop (DT) and Mini-tower (MT) – are also used in the GX620 range, but the GX620 gets a pint-sized fourth member too called the Ultra Small Form Factor (USFF).

Combining both series gives you four chassis and seven basic models to choose from, with image and BIOS compatibility throughout. The GX620 devices, with their bigger designation number, are the high achievers of the family. The difference, says Dell, is that the GX520s are for deployment as mainstream PCs, with perhaps a three-year lifespan before disposal, whereas the GX620s, with more complex motherboards higher specifications and better upgrade possibilities, are destined for more demanding environments and longer deployment.

Security-conscious businesses should also note that only the GX620 includes a TPM (Trusted Platform Module). This device helps to block hackers by providing hardware network authentication.

The key element that ties all the models together is the Intel 945 Express chipset. Besides performance advantages and new features, its newness makes it a good choice for longevity across a progressive rollout. Dell says it will offer the platforms for about 15 months.

SPECIFICATIONS

Processor choice is varied, with Celeron D and Pentium 4 options being supplemented by dual-core Pentium D chips in the GX620 range. The GX520 range and the smallest GX620 are limited to 2GB of 533MHz (PC4300) DDR2 SDRAM across two DIMM sockets, but the three larger GX620s have four sockets for up to 4GB.
