All-in-One 22" Desktop

This 22-inch all-in-one desktop integrates the computer and display into a single unit for office and home use. It ships with Windows 10 Pro 64-bit, a USB keyboard and a USB mouse so it is ready to run immediately. The Intel Core i5-2400 quad-core processor at 3.10 GHz with turbo up to 3.4 GHz handles everyday applications and multitasking. Integrated Intel HD Graphics 2000 drives the built-in widescreen LCD monitor.

Build integration and expansion

Gigabit Ethernet provides wired network connectivity without extra hardware. Internal expansion includes PCI and PCI Express x16 slots for add-in cards, while legacy parallel and serial ports support older peripherals. Multiple USB 2.0 ports free up connections for external drives, printers or other accessories. The 16X DVD±RW drive reads and writes optical media for software installation or data archiving.

Capacity and headroom

The 256 GB SSD offers fast boot and application load times for the operating system and core programs. Eight gigabytes of DDR3 memory supports typical office workloads and web browsing with several tabs open. Storage may fill quickly with large media libraries or modern game installations, requiring external drives. The integrated graphics and DDR3 platform limit performance in 3D rendering, video editing or current gaming titles.

Questions about this item

Does the i5-2400 reach its 3.4 GHz Turbo Boost under sustained load?

The i5-2400 can hit 3.4 GHz Turbo Boost for short bursts, but sustained all-core workloads will hold closer to the 3.10 GHz base clock once thermals stabilise.

How loud does the USFF chassis get when the PC runs all day?

The compact USFF form factor uses a small internal fan that becomes audible under continuous load; expect a noticeable but not extreme whir after extended use.

Do I need to buy any cables or peripherals to start using this all-in-one?

No — the box includes a USB keyboard, USB mouse and the integrated 22″ monitor, so only a mains lead is required to begin.
