I want want 6 drives in RAID 5 for the NAS. For the moment i'll buy just one.

I'm planing to build a NAS at my home because I have a TONS of movies, series and information and I would like to share it with other computers and smart TV. Right now i running low in space in my PC so I want to buy a new drive and I would like to use it at the NAS in the future. So there would be any problem if I use a 4TB WB RED in my PC?

Right now I'm using 4 Fan Corsair Air Series Static Pressure 140mm with red led and 2 120mm corsair fans that came with the Corsair Hydro Series H100i. It looks really cool but it's preatty loud. Any red or RGB led fans that are silent in both sizes (120 and 140 mm)?
