OptiPlex 3420 SFF business desktop

This OptiPlex 3420 SFF is a refurbished business desktop built around a quad-core Intel Core i7-6700 running at 3.40 GHz with 8 MB L3 cache. It ships with 16 GB of memory and a 512 GB SSD, running Windows 10 Pro 64-bit. The small form factor suits offices that need capable performance in limited desk space.

Sustained load on integrated graphics

Under continuous workloads the Intel HD Graphics 530 handles general business applications and multi-monitor output through its HDMI, VGA and two DisplayPort connections. The 64-bit quad-core processor maintains its 3.40 GHz base frequency across all four cores, while the 512 GB SSD keeps data throughput steady. No discrete graphics option is included in this configuration.

SFF installation notes

The slim chassis fits standard SFF mounts and provides front-access USB 2.0, USB 3.0, universal audio jack and DVD-RW drive. Rear I/O adds four USB 3.0, two USB 2.0, serial, RJ-45 Ethernet and line-out ports. Internal expansion is restricted by the small form factor; buyers needing additional drive bays or full-height add-in cards should verify compatibility before purchase.

Questions about this item

How loud and hot does the i7-6700 system get when running all day?

The small form factor uses integrated Intel HD Graphics 530 and a quad-core processor, so fan noise stays low and case temperatures remain moderate during extended use.

Which cables and display do I need to connect to the HDMI, VGA or DisplayPort outputs?

You need a monitor with HDMI, VGA or DisplayPort input and the matching cable; the desktop includes one HDMI, one VGA and two DisplayPort connectors.

Will my older USB 2.0 peripherals work with the USB 2.0 and USB 3.0 ports on this unit?

Yes, the system provides one USB 2.0 and two additional USB 2.0 ports alongside four USB 3.0 ports, so legacy devices plug in directly.
