This is an impressively compact system given its performance. It's always nice to see attempts to minimize the footprint of a desktop system without compromising on performance.
I am a fan of the console sized PCs with full sized GPUs. I own a traditional tower (Deepcool Genome 2), a Alienware Alpha, and a Node 202 (about the same size as here). I really don't feel like I am missing anything in the Node, where as the Alpha is as upgradable as a laptop. Too me it's a new sweet spot.
Given the specs. There is no surprise about performance. A decibel reading under load would have been a useful addition for some people. If there was mention. I didn't notice it.
