Hello e'rrbody. I got something that I need help with, particularly from people that have dealt with servers and the like. I just put together all of my spare parts and made something from them. They're mostly pedestrian mainstream parts, but I need to know if they will work for a home server. Here is what I have:

If these parts look familiar to some of you that's because they have been in and out of my other build. I still use that as my primary rig and now I have this one as well. The only new thing I have had to buy is the motherboard. I had the spare i7 but no motherboard to pair with it so I had to get one. Hell of a search as Z77 boards are hard to come by nowadays, but I got lucky and found this one refurbished. Color matched with my RAM sticks as a bonus. The PSU is overkill i know but I have it already so I might as well use it right?
But anyway will these work for a home server and what OS would be best? My use for it would be more like a NAS for backing up my main rig and serving my media collection for the time being. I have a lot of CD's and Blu-Ray movies that I'd like to rip and store on it. I'd much rather have a server than a NAS as I surely can find more uses for it in the future.
If I can't use as a server I'll just sell this as a whole computer minus OS and GPU. I know next to nothing about servers so any input will help a great deal. Many thanks in advance!
