Lenovo ThinkCentre M93z 23 Inch All-in-One PC, Intel Quad Core i5-4570S up to 3.6GHz, 16G DDR3, 512G SSD, DVD, WiFi, BT 4.0, Windows 10 64 Bit-Multi-Language Supports English/Spanish/French (Renewed)

This is my first all-in-one PC. I needed something to fit in a small space without a mess of cords, while performing well with decent built-in sound. This M93Z works great and it's built more solidly than I expected, even considering it is a Lenovo. Great deal with 16GB. I would buy this one or similar Lenovo again no question.After some research I chose the Lenovo M-series over some other similar ones because I wanted to mount it on a monitor arm rather than put it on the included stand. Not all (maybe very few?) all-in-ones have the VESA mounting screw holes as an alternative to their included stands. The one problem I ran into was the weight of the PC -- it's a bit too heavy for the arm I have. Just be warned. There are good quality arms or wall mounts that will take its weight though, just be prepared. You'll need an arm that can hold over 20 pounds.

Don’t buy this computers. They are not in a good shape. One of the corners was broken and a piece chipped. They are dirty and poor maintained. It shows on the pictures that it comes with a wireless mouse and keyboard but this is not true, they keyboard and mouse are cheap wired which none of the four that came with the computers that I bought are working. Lastly, I’m in the process of return two because of the poor conditions, and I have to pay for the return shipping cost and I can be charged a 15% “restocking fee” if they decided. I’ll post an update once I have completed the return.
