Wow. I could use that space on my desk. (Ours is a ten-year-old monster Dell...:-)
I've got a big flat screen monitor and full size keyboard
on my desk. So the size of the computer itself is
inconsequential by comparison. And some flat screens
now come with a bracket to mount these sorts of things
of the back of the monitor. (POOF! Footprint totally gone!)
And I would suggest 8GB of RAM (instead of 4) and definitely
the 128GB solid state drive storage option (instead of 64).
If you need more drive storage space, just plug in a multi-terrabyte
external drive to one of the USB3 ports.
(I say: 'BUY it - you know you WANT it...' LOL!)
