Eh.. For pro video editing you probably need a workstation with a fair amount of cores (6-10) although for non-professional video editing a 6700K or a 6800K will work just fine. For GPU's, it only really matters if you are using a codec that supports GPU acceleration. For storage you'll want a NAS, but for now two 2TB drives in RAID 1 will do and for an SSD something like an 850 EVO will work. For memory you can do 16-32 GB and that should work, speed doesn't matter but if you are doing long renders than ECC memory will be beneficial. Case and PSU dont reall matter, although your motherboard should work with all other components that you buy, but make sure it is a quality one (Maybe a WS board from ASUS)
