Ultra-Small Form Factor Desktop

The Dell OptiPlex 780 USFF is a compact desktop computer built around an Intel Core 2 Duo E8400 3.0 GHz dual-core processor with 6 MB L2 cache. It ships with 4 GB DDR3 SDRAM and a 250 GB hard drive. Microsoft Windows 10 Pro comes pre-installed for immediate use. This unit suits home office tasks and basic business applications.

Bundled Connectivity and Media

Integrated WiFi and Bluetooth adapters add wireless networking and peripheral support without extra hardware. A 16X DVD±RW drive handles disc reading and writing for software installation or data backup. Gigabit Ethernet via the Intel 82567 controller provides wired network access. USB 2.0 and eSATA ports expand storage and peripheral options.

Straightforward Setup

The ultra-small chassis fits tight spaces and uses standard DIMM 240-pin memory slots for any future RAM changes. Integrated Intel GMA 3000 graphics and ADI 1984A audio require no separate cards. Buyers who need more storage or discrete graphics should note the limited internal room and lack of expansion slots. Monitor is not included.

Questions about this item

Will the 250 GB hard drive be the first part that needs replacing?

The 250 GB Serial ATA hard drive is a mechanical component; plan to replace it if it develops bad sectors or audible clicking after extended use

Which limit appears first when the Intel Core 2 Duo E8400 runs at 3.0 GHz all day?

The 4 GB DDR3 memory fills quickly under multitasking, so the system swaps to the 250 GB hard drive and becomes sluggish before the processor hits its thermal ceiling

How loud and hot does the USFF chassis get with the DVD-RW and Gigabit Ethernet active continuously?

The ultra-small form factor uses a compact fan that spins faster under load; expect noticeable airflow noise and warm exhaust after several hours of constant operation
