Yup, that's only if you buy it from Lenovo configured that way. Most of the ones on eBay are sold without it so you would have to get the riser & support bracket from China (linked earlier in this thread) or buy the kit from Lenovo for around $330.
So I just bought my second M720q and I have two of these brackets and risers coming soon as well.
One M720q (G5400T) will be used for pfSense and the other one (i3-8100T) will be used for Plex.
Now to find a tinyminimicro or SFF box to replace my Blue Iris 813M. Leaning more towards an SFF box...
I found the riser...it is coming from China. As for the support bracket, I am thinking about 3d printing one to fit it. I don't think there are any other supports other than the riser and 4 port bracket.
