I want to turn an old system into a file server (P4 2.53ghz). Only downside is it has no SATA or gigabit networking capabilities. So if I were to do this I would have to get a PCI hard drive controller and a PCI 10/100/1000 nic card. What kind of transfer rates could I expect with sharing the PCI bus like this? Would it be good enough to stream HD movies from?
