Ask HN: Pre-Built Desktop for Deep Learning

I am seriously considering buying a pre-built desktop to get into Deep Learning. List of the important components is in my comment below. The GPU in the pre-built desktop is a regular 11GB 1080 Ti, not the FE, but the FE was the only NVIDIA 1080 Ti I found on pcpartpicker.

Q1: Are there any reasons you would think this is NOT a good system for a beginner?

Q2: I plan on ordering it without an OS and installing Ubuntu myself. Is it reasonable to expect this process to go smoothly, or is a Windows/Ubuntu dual boot setup better?

Thank you!
