Business owners who are shopping for a new system to expand their business might be interested to check out Lenovo’s latest ThinkCentre machine, the M75e. The computer will be available in both small form factor mini-tower and standard tower designs, starting at $504 and $524 respectively. The baseline configuration includes a 2.8GHz AMD Sempron 145 AM3 processor, Windows 7 Professional, 2GB of DDR3 RAM, integrated AMD GPU that is capable of powering two displays, 250GB hard drive and a three-year warranty. If you’re a little flusher, you could also upgrade to an Athlon II or Phenom II CPU and up to 16GB of RAM.
