500gb is recommended for all the downloads of games you are "anticipated" to download. Not sure if there is that many games that are supported on Linux at the moment. I know about 10 of my games are, but i will still be trying it. Linux is classified in "Beta" because it is finished to an extend, just the OS though. Drivers and other things are not included. That is where Linux enthusiast must use either terminal or the internet to find the proper drivers for their cards (Nvidia at the moment, AMD will be coming later). I will be installing it here in a few, going to see if i can add the option to dual boot. I used Linux already to try and run Steam games and it ran very well. If it is anything like that, everything you need will be online, just have to search for it. Furthermore, one thing i noticed for Linux was there is no support for Fan control drivers, so i had to keep the graphics a little lower than i would on Windows, or else my card would get really hot! These are just preliminary observations from myself.
