I am completely new to Raspberry Pi, and don't know a lot about it. My knowledge on hardware, software and programming (except for basic Python) is also very limited.
However, I read you can make a NAS out of a Raspberry Pi. I browsed through some questions here, and even saw some tutorials, but in every case it seems that only low-power NAS can be made from Raspberry Pi.
I'd like to create a NAS that gives me instant access to files and/or streams HD videos.
Is this possible to accomplish with a Raspberry Pi?
If so, will it still be cheaper than a regular NAS solution?
