I do IT for a living. We had some floods here in Mississippi. Some of my clients offices were up to 1' in water. Had a Lenovo with 6" of water in it, 1/2" under the hard drive. This guy was just close enough to swap out the hard drive that came with it (properly pre loaded with W10!) and install my old Win7pro from the damaged computer. It came up and all I had to do was let Windows update install a couple of new drivers. The network interface was working, so all I had to do was to plug a Ethernet cable into it. I removed the USB wireless adapter that came with the refurbished computer which will not be needed in the office environment. I and my client are quite happy. The case had one small dent, but was clean inside and out. Thanks!
