I'm thinking of getting a few HDDs (say, 3-4x 250ghz) and set up the computer to be a storage server for my 3 computers (adding a 4th later). Most probably going to be used for MP3s, Videos and games. Work files will be stored there, but nothing that requires high security, and ample backups will be created. Is there any problems associated with this? If someone downloads a virus and stores it into this computer, will this computer have problems? I'd also need some advice on setting up (striping) RAID on 3-4 HDDs. I do know that I'll have to buy all 3-4 HDDs brand new to do this (I don't have 250gb disks to start with anyway), and probably a RAID controller. Anyone has a good site I can refer to to set these up on SATA drives? Oh yeah, this is on my first PC, info should be available on this site. ATM, there's space for 1 more SATA HDD, so I'll need a card or some way to add another 2 SATA HDDs. On physical inspection, I've got a couple of PCI slots free.
