Better? No absolutely not. Capable? Without a doubt. I have a multi bay nas and it's like 1/6the the size of my pc case. My nas also makes removing and replacing drives trivial. There's a million guides online for my particular nas already and software written with it in mind. It also draws a lot less power than my gaming pc and has a lot quieter operation.

It's difficult for me to accept it's better given all the above.
