Previous sales of similar ThinkCentre M700 Tiny’s:
I have a similar model (from Amazon) and I love the form factor. It’s relatively new, but, so far, it has been solid.
Edit to add:
BTW- there was some concern for previous offers about the DisplayPort output. I can verify it will drive a DVI-D monitor with just a conversion cable. (Which means an HDMI conversion cable will also work for video. Can’t vouch for audio, etc. though.)
