I'm planning to build a computer to be used as file server. The computer would have 2 Seagate 320 GB SATA2 in RAID 1. I have the spec in my mind, but would like some advise before actually buying and building the computer. It would be used as a file server for 3 or 4 graphic designers who would take source files from the server, and, after completing the final design in their own work stations, copy the final design back to the server. The data exchange won't be that big, maybe around 1-2GB per day. It doesn't have to be very fast, the security and reliability of the data is more important. My current planned spec: -Athlon 64 3000+ AM2 -Asus M2NPV-VM (onboard video card) -2 x Seagate 320 GB SATA2 in RAID 1 -Corsair DDR2 PC 5400 512MB -DVDRW Pioneer for backup -Enlight Case with 330W PSU -Generic keyboard and mouse -Old Philips 15" CRT monitor The server and the workstations will be connected via 100Mbps network, I've considered upgrading to gigabit network, but would like to see the current network performance first before deciding. As for the OS, what would be best for it? Will Windows XP be sufficient? Or do I have to use Windows 2003 Server? The clients all use Windows XP Pro. Any advise before I buy the components?
