50 simultaneous users will require more than a bargain desktop PC. I would go for low-end server hardware, which will get you ECC memory and more SATA ports. The cost is probably not significantly more than a _good_ quality desktop system. You may want to allow for some expansion, 2 To may grow into 3 To over time. Also plan for backups. You may want to use LVM and leave some disk space unallocated to you can create snapshots and make backups to external USB drives or another network server while the system is up and running. My personal criteria: - decent power supply - space for 4 3.5" hard drives. - 4 memory slots, so I can go to 8 Go memory without breaking the bank - at least a dual-core Xeon or AMD processor which supports ECC memory - 4 or more available SATA ports on the motherboard - 1-2 1000BASE-T network interfaces. You could go for a RAID controller, but RAID1 (mirroring) has little overhead in software, and you can buy 2 extra hard disks for the price of the controller.
