Since 1 dec 2016 I got a new job and was allowed to choose my own laptop, but I choose a NUC6 i5 with 2x 24" screens, and put Linux Mint 18 on it. The first few days it totally froze on me a few times, but after upgrading to Mint 18.1 and Cinammon 3.0.6 it has now run uninterrupted for 2 weeks already.
I have the CPU temperature and performance monitor in the footer, it is currently 39.3 deg Celsius without any noise at all (I have no music on so it is totally silent here). I run PhpStorm, 2 Firefoxes with in total 21 tabs, a terminal with 3 tabs, 1 vagrant VM, 1 Chrome browser with 4 tabs, 1 file manager and 1 PDF viewer. It is not cheap, but a lot cheaper than laptops with the same specs. Colleagues with Win of Mac laptops do have their fan running audibly.
My previous PCs were a MacMini and an MacBookAir, but I would not want to switch back.
