Summary: This is my second Lenovo desktop and I like the M57 even better than the M55. The 64-bit Windows 7 is a great OS and I have had no problems with it. The 4GB of memory and the 1TB HDD gives me plenty to work with.
Summary: The unit came in two days. and three days after receiving it it automaticly upgraded to Windows 10. Witch was pleasant surprise. Set up was easy and quick. Preformance is exilant. More then I expected.
Summary: I love this system for it's value. It works great. I already upgraded to Windows 10. It is a good basic internet machine. The hard drive is large, and probably new. The drive is a little noisy. But it is running fine.
Excerpt: I ordered a Lenovo M57 TW-2.3-750GB-3GB, Intel Core 2 Duo, Windows 7 Home Desk Top. The Unit came on time but had a Window Vista Product Key instead of a Window 7 key. Took 4 phone calls with a wait of 45 min. each to be told they are the wrong depts.
Summary: I needed a computer with a dedicated serial port and to use for print server on network. This is an easy computer to work with, case opens with no tools all parts easily accessible. This was good because the fan was very noisy, tried all adjustments, used machine oil to lubricate without success.
Summary: When it came time to retire our old office desktop we just couldn't beat the deal we got on this PC. It's the perfect machine for basic word processing, web surfing etc. It has plenty of input options and even came with a new keyboard and mouse.
Summary: Good news: 64 bit OS for $179.00. Bad news: 2 gigs of ram, basic video capability. Windows 7 works fine and upgraded fine. No bloatware. It's a used machine and with 2 gigs of ram it runs a bit slow. You can upgrade the video and the ram.
