Questions about this item

Does the workstation ship with a monitor, keyboard and mouse or do I need to supply them separately?

The system includes only the tower with Windows 11 Pro installed; monitor, keyboard and mouse are not included and must be purchased separately.

With 192 GB DDR5 already at the motherboard maximum, is there any reason to choose a lower-capacity configuration?

The board supports up to 192 GB DDR5, so this build already provides the full memory ceiling; a smaller kit would only be chosen to reduce cost.

What does the 4.4 GHz base clock on the 12-core Ryzen 9 9900X3D mean for sustained workloads once the liquid cooler is running?

The processor runs at 4.4 GHz base and can boost up to 5.50 GHz; the 240 mm liquid cooler is designed to maintain those speeds during extended compute tasks.
