Overview

A sixteen core Intel desktop processor with integrated graphics drives this slim black business tower, which also has DDR5 memory, an SSD and a TPM chip. It runs Windows Pro and has an Ethernet LAN and several display outputs.

Strong processor performance in a compact case suits office work and multitasking, and two 4K monitors can be driven from the outputs. Input devices come bundled. The listing contradicts itself on the USB port total and the keyboard type.

Who it's for

Office users, accountants and developers who run heavy multitasking and two high resolution screens will use the processor power. Gamers and video editors who rely on dedicated graphics should look elsewhere.

Pros and cons

Pros
  • Fast sixteen core processor
  • Dual 4K monitor support
  • Memory and storage expandable
  • Keyboard and mouse included
Cons
  • Integrated graphics only
  • USB port count listed inconsistently
  • Keyboard type described two ways
  • No webcam or display included

Performance notes

Multitasking speed comes from the high core count processor and DDR5 memory, while the SSD cuts load times. Integrated graphics share system memory and drive the two monitors, which suits office use but not games. Cooling is by air in a quiet slim case.
