I am building a new PC and I require as much storage as possible.
So plz suggest a mobo which offers maximum number of SATA ports and a case which can hold all those hard drives.
Gaming will be moderate at best so I dont need major cooling or excessive overclocking features. The sole purpose of this PC is to get as much storage as possible without spending too much on other components.
I don't know if 500W would be enough for that server but from reading the specs that's the kind of server power supply supports by the Norco. It also supports regular ATX power supplies like the one suggested above.
I don't have experience with either. It seems to me cards that directly support the SFF-8087 interface would be more advantageous.
As for which mini-SAS card, I think you need to look carefully into compatibility and make sure the drives you plan to use are supported. Besides that, what you plan to do with all this storage should dictate what performance you need.
