The ThinkCentre S50 desktops feature a tool-free chassis design, which simplifies and enhances usability. Encased in a durable steel chassis, components inside the machine, such as the hard disk and memory, can easily be removed by the customer, making the PC serviceable and upgradeable, helping to limit the downtime and cost associated with on-site support. Cable routing is bundled out of the way for easy access to components and cable ends and user touch points are colored blue to be easily identified by the user. ThinkCentre S50 desktops also feature an innovative "caddy" that surrounds the hard disk drive, locking it into place without the use of tools or screws. Rubber bumpers on the caddy decrease vibration and deliver quieter operation. Other mechanical improvements have been made to the overall design of the ThinkCentre PCs, including improved airflow and reduced noise.

The ThinkCentre S50 is a full-feature enterprise PC offering image and platform stability in an extremely small form factor. The ThinkCentre S50 is 62% smaller than a standard IBM desktop. It allows for flexible placement, either horizontally or vertically. The ThinkCentre S50 features allow customization and easy upgrading, which is uncommon for a small form factor PC.
