Lenovo ThinkStation C20 Review


Big computers generally mean big performance, but does a PC need to be imposing in order to blitz through the benchmarks? Lenovo's ThinkStation C20 is the baby of the range when it comes to physical size, but with dual Intel Xeon processors and...

Lenovo ThinkStation C20


The C20's interior is somehow both spacious and compact at the same time: the chassis has expansion space for two additional internal hard drives, two PCI cards, two PCIe x16 cards (one is electrically x4), a PCIe x1 card, and four memory DIMM slots....

Dual CPU Xeon power. ISV certification for many professional programs. Rack mountable. Compact for a full-blown workstation. Capable of driving two 30-inch panels simultaneously. Card Retention. 3-year warranty. Quick and easy to service

Pricey. No USB 3.0 or FireWire. Could use more memory slots

The Lenovo ThinkStation C20 should be at the top of your list if you're looking for an ISV-certified Windows 7-based workstation. It costs a pretty penny, but if you're working on multi-million dollar projects, the system's speed and serviceability...

Review: Lenovo ThinkStation C20 Workstation


Workstations are the backbone of most businesses because they are powerful, reliable, and they usually get extra support after the sale. Workstations are also well known for being large and heavy because of all the hardware that is packed inside....

Lenovo ThinkStation C20: A compact, powerful and pricey business PC


Lenovo's new workstation is also useful as a sophisticated graphic artist's tool.

At $6,674, the ThinkStation C20 obviously comes at a premium price -- but, as its performance numbers prove, it's a premium computer. For graphics professionals, the Lenovo ThinkStation C20 could represent a real increase in productivity. You just...

Lenovo ThinkStation C20 review


The Lenovo ThinkStation C20 was designed to have a substantially small footprint without sacrificing performance. Having the ability to attach up to eight displays also makes it ideal for tracking several trading boards at the same time - as well as...

Lenovo ThinkStation C20 review


Lenovo claims its ThinkStation C20 PC is the world's smallest dual processor workstation. It's certainly compact, but is it as powerful and expandable as the competition? Read our review to find out.

There’s a lot to like about the ThinkStation C20. It’s fast, quiet, relatively compact and comes with a professional-level graphics card as well as a lengthy warranty. The interior could be better designed and laid out though, especially if you want to...
