This minitower was shipped quickly and received in good shape; it was a bit sluggish so I upped the Ram from 4GB to 12 GB, bumped the processor to a 4-core A8-6500, and swapped the power supply from 280W to 480W. Windows 10 I am not too fond of; came from WinXP.
This ThinkCentre M81 is not the fastest or newest system, but it worked very well. Although slower than the top of the line Intel Core i3, i5, and i7 processors, it is certainly faster than some of the brand new systems available in the store right now. It came with 4GB RAM; 2 sticks of 2 GB were installed, and two slots were empty. It has a 64bit version of Windows, so the RAM can be easily upgraded without issue. It included a "refurbished computer" version of Windows 7, including an authentic certificate of authenticity. The case itself was a little scratched up, but for $140, it is still a great deal. The optical drive is an older "combo" drive that reads, but does not burn DVD's. Windows 7 updated to Windows 10 without a problem. For a basic, day to day office, email and web surfing system, it should work great.
