Lenovo is seeking to embed themselves in a deeply crowded market, by reviving the "ThinkStation" line of hardware that waned in the face of companies like Dell and HP. While modern workstations are almost exclusively composed of machines built by a few top-tier vendors, Lenovo thinks that due to such stagnation in the market that there is room for one more.
Thus, two new ThinkStations will be arriving, the S10 and D10, both of them aimed at workstation environments or office settings. They don't expect to rely on the name alone to carry their weight, and have lined up some big companies already such as branches of AT&T.
The machines will be based either off the Quad-core Xeon 5400 series (D10) or the Core 2 Extreme series (S10), and an unspecified Nvidia GPU. On top of that, they are making sure the systems are Energy Star 4.0 compliant and feature such goodies as 80 Plus rated power supplies. The systems will run from $1200 to over $1700 depending on configuration.
Even though they decided to drop the IBM branding on their laptops recently, they haven't done such with these new workstations. Presumably, if the workstations see success, they will probably follow in the footsteps of the laptops as well, dropping the name.
