@sandbag_attitude I bought a NUC7i3BNH 2 months ago, equipped it with 16 GB RAM and a 512GB Samsung SSD and use it as a VM server with Ubuntu 18.04 as host and client OS. Works flawlessly.
@heurekus Thank you for answering! How about the noise levels? And would you be able to fit a second drive (HDD) inside?
@sandbag_attitude Noise level is very low, almost inaudible, both when the server is mostly idle and running at 100% CPU power. Not sure if a second drive would fit in, I didn't try. Bought the bigger NUC case so a 'normal' 2.5" SATA SSD would fit in.
@sandbag_attitude Never tried graphics as I use the NUC as a headless server. Installed using the text based installer.
