The Lenovo ThinkCentre M78 tower is an excellent choice for large companies that need a reliable, responsive, and efficient computer. This system is powered by a fast quad core processor, which is great to have when navigating your workflow.
Note: these computers do not have an Operating System loaded. You can buy it with no operating system loaded or choose between Windows 10 Home or Professional to be loaded.
With an old quad 4 CPU, it runs quietly and very nicely. It now inhabits my living room with a 25" monitor for visitor's use. Great for emails, shopping, research, and children's games. Just add an inexpensive video card for HDMI and everybody is happy. :)
