ThinkStation S20, Intel Xeon E5504, DDR3 4GB, 150GB, SATA, Gigabit Ethernet, Black
All Lenovo ThinkStation workstations share common features that showcase Lenovo's dedication to quality, including quiet acoustics, a cool thermal design, RAID standard, back-lit front I/Os and tool-less upgrades. However, both the S20 and D20 also feature unique qualities that makes them a great match for your individual needs.
The single-processor Intel Xeon ThinkStation S20 is the ideal mid-range workstation solution. Offering a robust 625W power supply, even the S20 allows for easy upgrades and offers support for two high-end powered graphics adapters. It is ideal for 2D digital content creators and users of mid-range CAD and EDA applications.
The dual-processor Intel Xeon ThinkStation D20 is a computational powerhouse. Offering 12 DIMM slots and RDIMM technology, the D20 supports up to 192GB of blazing-fast DDR3 memory and is perfect for users of memory and CPU-hungry applications like high-end CAD/CAM/ CAE, 3D digital content creation and professional video editing software. The D20 also offers 1394 and SAS support standard, support for NVIDIA's Tesla C1060 GPU computing solution and NVIDIA SL on select Quadro cards, as well as more expandability options than the S Series.
