Questions about this item

Does the 128 GB SSD leave enough room for large project files over time?

The 128 GB SSD holds the operating system and core applications, but large media libraries or project archives will require external storage or a secondary drive upgrade.

How loud does the system get when the i7-9700 runs at full speed all day?

The all-in-one chassis uses a single fan to cool both the 3.0 GHz octa-core processor and integrated UHD 630 graphics, so sustained workloads produce audible airflow noise at the top vents.

Which peripherals are already included so I can start working immediately?

A USB keyboard and USB mouse are bundled in the box, along with the integrated 27 inch 1920 x 1080 display, webcam, Wi-Fi and Bluetooth 5.
