I purchased this computer to use as an ESXi VM host. I installed ESXi without issues and the thing was running great. Then I decided to change directions.This is an amazing workstation for conducting home business. The wireless antenna is excellent for those far away working spaces but that's not the best part.With Lenovo's Tiny series line of support, you can buy different types mounts to include VESA mounts for the backs of monitors. I was able to mount this computer under my desk, and completely out of sight. Additionally, It's quite and functions perfectly.This specific model came installed with Windows 10 Professional (not home). That is a huge value in my eyes. The price of the OS alone, covers the price of the computer.Support was amazing. When I made the decision to switch back to Windows from ESXi, I realized that I didn't capture the license (a sticker was not included on the enclosure). I contacted Amazon support and within minutes they helped me to get a fully functioning Windows 10 64bit Professional running, without problems.Now, I use this computer as my primary PC. I did not expect to do that. I run Hyper V in the background for setting up my VMs and then offload them to a different PC.I just purchased the i3 version to gift my son. I expect that it will meet his needs as well. For the price and performance, you just can't beat these Amazon-Lenovo deals!I Love Amazon and Lenovo!
