LENOVO® THINKSTATION® C20 AND C20x
Lenovo introduces the all-new ThinkStation C20 and C20x, compact, premium 
workstations for businesses that have space-constraints and require dual-CPU 
horsepower. Available in two models, the ThinkStation C20 offers traditional 
and compact dual-CPU workstation performance in an unprecedented form 
factor. The ThinkStation C20x is a true testament to Lenovo’s exceptional 
engineering, achieving what many thought to be an “impossible design”.
The ISV-certified ThinkStation C20 and C20x are engineered from ground up 
for the Financial Services sector, Computer-Aided Design (CAD) and Digital 
Content Creation (DCC) centers. They are the world’s smallest1 dual-CPU 
workstations with no-compromise performance2. These workstations allow 
professionals to fit more number-crunching capabilities in less space, as 
compared to traditional and compact dual-CPU workstation solutions.
Powered by Intel® Xeon® 5600 series processors, the ThinkStation C20 and C20x 
significantly improve performance and productivity as against prior-generation 
technology. These enterprise-class processors offer Turbo Boost Technology, 
which can intelligently adjust the CPU’s performance and power usage, 
depending on the user’s workload. Further, the Lenovo Enhanced Experience for 
Windows® 7 enables faster start-up and shut-down times among other security 
and back-up features, enhancing end-user productivity. The ThinkStation C20 
and C20x also come with Error Correcting Codes (ECC) memory, providing 
greater data accuracy, improving system uptime and protecting against memory 
errors. For leading-edge graphics, Lenovo has partnered with NVIDIA® and ATI® 
to bring you the latest in professional workstation graphics adapters, yielding 
superior application performance and stability.
The ThinkStation C20 and C20x are also the perfect choice for businesses 
that require a smaller, easy-to-manage workstation and maintain dual-CPU 
performance. A tool-less interior enables quick and easy maintenance and 
upgrades of key components, without ever having to reach for a screwdriver. 
Equipped with a spill-resistant, recessed handle, the ThinkStation C20 and 
C20x are optimized for rack environments. A standard 42U rack traditionally 
fits up to 10 compact workstations, but with the ThinkStation C20 or C20x 
customers can now install up to 14 systems. Front-access media ports with 
illuminated I/O icons allow you to easily connect devices to the right I/O ports, 
even in dark environments. The recessed power button design prevents 
accidental shutdowns that can potentially cost users, hours of their hard work.
