Which system may feature a tool-less removal system for its board?

The correct answer focuses on the workstation tower, which is designed for ease of maintenance and expandability. A workstation tower often features a tool-less removal system for its motherboard, allowing technicians to easily access and replace components without the need for additional tools. This design facilitates efficient upgrades and repairs, making it user-friendly for service technicians who need to perform routine maintenance or resolve issues quickly.

Workstation towers are typically larger than mini towers and other compact systems, providing more space for advanced hardware configurations and additional cooling options. They are particularly well-suited for demanding applications in professional environments where time and efficiency are critical, further justifying the implementation of such a tool-less design.

In contrast, while mini towers, all-in-one PCs, and desktop cubes are designed with certain form factors and might prioritize compactness, they often do not focus as much on tool-less operations for significant components like motherboards. The design constraints of these systems sometimes necessitate the use of tools for assembly and disassembly, limiting ease of access compared to workstation towers.
