Because of OE is free and you don't need a Windows Licence, Windows Updates, AntiVirus Updates, no need to install Drivers.
You can install it faster than Windows, it needs fewer HDD Space,...

Yeah but with an ssd, the speed differences are minimal, in terms of load times. I mean, to spec out a nuc costs about 500-600 bucks, and a windows license isn't that much more, given the amount f additional flexibility and functionality you get. You cant get a virus if you aren't screwing around with your htpc and browsing the internet. If all you use it for is to strictly access media in your home network, then you don't need to run antivirus software... I don't. I could understand this argument about price from people building raspberry pis, but a nuc is a real computer, and the headaches i saw from ppl on the first page just trying to get it to work seems like a lot of aggravation, but then again i haven't read the entire thread, maybe the later builds are much more seamless.
