Hi I currently have failing hard drives in my pc, that i use to store everything.. so I am taking the opportunity to move to a NAS style solution. What is your opinion on a custom built media/storage/server machine, vs a prebuilt NAS device that allows you to swap in/out hard drives? cost vs stability vs features vs etc.? I am steering towards a prebuilt NAS for around $700-$1000. this is also my first NAS buy and i have only done little research.
