Compact gaming desktop

This Lenovo ThinkCentre M800/M900 small-form-factor PC targets gamers who want a space-saving tower. A 3.20 GHz Intel Core i5-6500 quad-core processor boosts to 3.60 GHz and is paired with 16 GB DDR4 memory. An AMD Radeon RX 550 graphics card with 4 GB DDR5 drives the visuals. Windows 10 Pro 64-bit comes pre-installed.

Build integration

The slim chassis fits tight desk spaces and uses standard DisplayPort output for 4K monitors. Dual storage — 256 GB SSD plus 1 TB HDD — gives fast boot and room for large libraries. USB 3.0 ports handle quick peripheral transfers and the integrated Wi-Fi adapter removes the need for a separate network card. Maximum memory supported is 64 GB for future upgrades.

Included peripherals

A bundled RGB keyboard and RGB mouse arrive ready to use, adding coloured backlighting without extra purchase. The Windows 10 Pro licence enables domain join, BitLocker and remote desktop features for professional or home-office use. The 90-day warranty covers the whole system during initial ownership.

Questions about this item

When does the AMD Radeon RX 550 4 GB DDR5 become the bottleneck in sustained gaming?

The RX 550 Phoenix Edition has 4 GB DDR5 memory; in extended sessions the frame buffer fills before the CPU hits its turbo ceiling, capping performance at the GPU's memory limit.

How loud and hot does the small-form-factor chassis get when the i5-6500 and RX 550 run all day?

The compact ThinkCentre case uses a single system fan; under continuous load the CPU holds 3.20 GHz base clock while the RX 550 stays at its rated clocks, so noise and heat remain at typical office-desktop levels.

Which display cable must I already own to get 4K 60 Hz from the DisplayPort output?

The desktop provides a DisplayPort connection that supports 4K resolution; a standard DisplayPort 1.2 or newer cable is required to drive a 4K monitor at 60 Hz.
