It features Intel Sandy Bridge chipsets and processors and was later upgraded to Intel's Ivy Bridge Core i5\i7 and Intel Xeon processors from four cores (e.g. Intel Xeon E5-1620 v2) up to twelve cores, such as the high-end model Intel Xeon E5-2697 v2. E32 
On August 21, 2013, Lenovo introduced the ThinkStation E32 professional workstation that is available in either a tower or 12.9L small form factor chassis. The E32 incorporates the latest Intel Haswell chipset and supports the Intel Xeon E3 and 4th generation processors as well as the Intel Core i7 and Core i5 series processors. The E32 supports both on-board Intel HD Graphics P4600 as well as NVIDIA NVS or Quadro 3D graphics cards, up to the K4000. The E32 supports up to 32 GB of 1600 MHz, DDR3 ECC memory in both form factors and has USB 3.0 ports on the front and rear of the chassis for a total of six USB 3.0 ports. As are all Lenovo ThinkStations, the E32 is fully ISV certified for applications suites from Autodesk, Adobe, Dassault Systèmes, PTC and Siemens, as well as many others. The E32 makes an ideal entry-level platform for CAD and AEC users. Both the tower and SFF configurations are reliable and "green," offering 80 Plus Platinum certification with up to 92% power efficiency. Due to the integration of the Intel Haswell microarchitecture and Microsoft officially ending support for the Windows XP operating system in April 2014, the E32 is the first ThinkStation model that does not support the installation of Windows XP. 2012

D30 
The ThinkStation D30 is a full-sized traditional tower workstation released in 2012. As is typical for ThinkStations, the front panel features a perforated honeycomb shaped pattern. The D30 can hold up to two Intel Xeon eight-core processors that feature hyperthreading in order to support the processing of up to 32 simultaneous streams of data. Video is powered by Nvidia Quadro graphics cards. The D30 scored a very high 25.31 points on the Cinebench test of 3D rendering. For comparison, the late 2012 Apple Mac Pro only scored 7.36 points on the same test. In a review of the D30 PC Magazine wrote, "Sometimes, you just need to bring out the big stick, and the Lenovo ThinkStation D30 is that big stick. The sheer power of the dual eight-core Xeon CPUs plus the ability to add on more powerful Nvidia Quadro cards means that this is a system to scorch project deadlines in minutes rather than hours, or hours instead of days. Our last dual-processor workstation Editors' Choice was the Lenovo ThinkStation C20, which amazed us by putting dual Xeon CPUs in a more compact chassis. The Lenovo ThinkStation D30 now usurps that mantle, as the dual-processor workstation Editors' Choice. It wins with power, expandability, and a ruthless devotion to get your project done before any of your rivals can." C30 
The ThinkStation C30 is a high-end dual-processor workstation designed for use in video editing, engineering, and finance. The C30 is slightly smaller than a full-sized tower but still comes with two PCI slots, two free PCIe x16 card slots for graphics cards, a free PCIe x4 slot, and space for two free hard drive bays. Two Intel Xeon E5-2620 processors, 16 GB of ECC DDR3 system memory, an Nvidia Quadro 4000 graphics card, and a 500 GB hard drive come standard. There is an option to rack mount the C30. PC Magazine wrote, "The Lenovo ThinkStation C30 is a very good dual-processor workstation. It is a powerhouse for the space constrained financial, DCC, or engineering user in your organization. The system therefore comes highly recommended, but its roomier, more powerful, and more expensive big brother the Lenovo ThinkStation D30 holds on to the Editors' Choice for dual-processor workstations for the time being for having a lot more power and being more flexible for future upgrades." 2011

E30 
Announced in March 2011, the E30 workstation could be equipped with either Intel Core i or Intel Xeon processors. The workstation could be equipped with either 80GB or 160GB solid state drives. Discrete graphics were available on the workstation, in the form of NVIDIA Quadro or NVS graphics. When the E30 was launched, Tao Gu, the executive director and general manager of Lenovo's Workstation Business Unit said, "We created the ThinkStation E30 workstation to offer extremely powerful processing on a software-certified solution at desktop prices."

SLASHGEAR stated that they "had trouble slowing the C20 down – this isn’t a PC where opening a few dozen browser windows will cause lag – and it stayed admirably quiet too (though fan noise did ramp up as the system was stressed during benchmark testing)". The reviewer also stated that the price would be far too high for most people to afford. The reviewer summed up the workstation by saying, "Graphics professionals, video editors or anyone looking to do vast amounts of crunching in minimal amounts of time, however – and without turning their office into a server farm – should definitely be considering the C20." In addition, since the machine was designed as a workstation used by graphic professionals and video editors it was not intended to replace high end gaming machines. PCMag received the workstation positively, awarding it 4 out of 5 stars as well as an Editors' Choice award. The workstation has been certified by several ISVs, including:
