Hi I want to build a massive storage pc to keep all my movies, series and games. I'll need 20Tb to start but I need a configuration that allow me to add more storage in the future. I'll appreciate any advice in hardware as and in configuration (to use RAID or not). I will use windows 7 system and will be copying the info constantly to all kind of usb devices so will need as much usb ports as possible. Thanks in advance and sorry for my english.
