Time For A New File Server

Hi all,

Looking to build a new file server to replace my aging HP Windows Home Server and looking for suggestions. Here's what I'd like to do:

-Full size case so I can add lots of space
-Would love hot swapping but at least ease to which I can install the drives
-Server Media to Media PCs/Raspberry Pi's throughout the house
-Fairly quick serving over mostly ethernet (a little wireless for laptops but obviously this will be slower)

What do folks recommend? I keep seeing the fractal design cases come up as a start...if you like those, what other hardware given this needs more serving capability and minimal graphics, etc.

I saw an article on Anandtech but its more than 3 years old some I'm sure some better options exist.

Thanks!
