The main use will be storage, however I want to be able to use it for more when needed. (ftp backup for websites, plexmediaserver, small gameservers, etc)
I went with the Fractal R5 because its silent and ofcourse the 8 x 3,5 inch slots for when I want to add some drives.
The Fractal Design Node 804 seems it will do but I'm not sure if it will be as silent.
For the RAM I was thinking about Kingston ValueRAM 8 GB ECC DDR3-1600 but if ECC isn't needed for this build then maybe Kingston ValueRAM 8 GB DDR3-1600 ?
I went for the Seasonic PSU because it doesn't have a fan and will be silent. I couldn't find any corsair ones without a fan.
