Dell OptiPlex 990 business desktop

The Dell OptiPlex 990 is a business desktop built around an Intel Quad-Core i5 processor and 8GB of DDR3 memory. It ships with Windows 10 Professional 64-bit pre-installed and includes a USB keyboard, mouse and Wi-Fi adapter. The compact chassis uses the Intel Q67 Express chipset and provides integrated Intel HD Graphics 2000 for display output.

128GB SSD capacity and DDR3 headroom

The 128GB solid-state drive holds the operating system and a modest set of business applications, but leaves little room for large media libraries or multiple virtual machines. Eight gigabytes of DDR3 memory handles typical office multitasking and web browsing, yet memory-intensive workloads such as heavy database work or modern creative suites will exhaust the available headroom quickly.

Upgrade path from older OptiPlex towers

This system replaces legacy desktops that still rely on mechanical hard drives and dual-core processors, delivering faster boot times and snappier responsiveness. The jump is worthwhile for offices standardising on Windows 10 and SSD storage, while users needing discrete graphics, additional drive bays or newer CPU architectures should look elsewhere.
