Ready-to-Work Desktop with Dual Monitors

This Dell OptiPlex 3090 desktop arrives as a complete workstation kit. It pairs a 10th generation Intel Core i5-10505 processor with 32 GB of DDR4 memory and a dual-drive layout of 1 TB SSD plus 1 TB HDD. Windows 11 Pro is pre-installed, and the box includes two 24-inch monitors, a wired gaming keyboard and mouse, plus RGB speakers. The system weighs 11.25 kg and was released in 2020.

32 GB DDR4 Memory with Room to Grow

The board holds 32 GB in a single module and supports up to 64 GB total across two slots. This leaves one slot free for a straightforward capacity upgrade without removing the existing stick. The memory type is DDR4 only; other generations will not fit.

Suited for Office, Study and Home Multitasking

Buyers who need an instant multi-screen setup for documents, video calls or classroom work will find everything included. Users who require a discrete graphics card for modern gaming or GPU-accelerated rendering should look at a different system. The compact chassis also limits internal expansion for additional full-size add-in cards.

Questions about this item

What does the 32 GB DDR4 memory actually let me do on this OptiPlex 3090?

The 32 GB DDR4 module runs in one of two slots, leaving the second free for a future upgrade to the 64 GB maximum supported by the platform.

Which interface does the 1 TB hard drive use and what throughput limit does that impose?

The hard drive connects through SATA, so its sustained transfer rate is capped by the SATA bus rather than by the drive itself.

What physical space and mounting provisions do the dual 24-inch monitors require?

Two 24-inch LCD monitors are included; each has a standard VESA mount pattern and together they need a desk area wide enough for both screens side by side.
