Review: Dell Dimension C521 - PC Mag
The compact Dell Dimension C521 desktop PC has been reviewed over at PC Magazine. 'Housed in a compact BTX case that's just a smidge larger than that of the XPS 200, the Dimension C521 is a relatively small desktop. The slight increase in size is a result of its greater functionality; it has space for three half-height expansion cards (one PCIe x16, one PCIe x1, and one regular PCI) and uses a desktop-size optical bay, while the XPS 200 has only two slots (one PCIe X16 and one PCIe X1) and uses a notebook-class optical drive. This means the C521 is more expandable, giving you more choices in case you want to upgrade the dual-layer DVD writer drive. The free optical drive bay in the C251 is also a boon for those thinking about upgrading to a third-party Blu-ray or HD-DVD drive in the future.'
