The good part is that you can upgrade ram/storage/interfaces. The bad part (as far as a tidy integrated package) is that they have external PSUs.
I have a trouble-free HP G series but it isn't clear to me what would differentiate it from the equivalent Lenovo or Dell.
The next interesting task is to add an external GPU [0] to make it a modular computer similar to the Snow White concept [1].
