I've been looking at some of the pulled Server NIC's online, dual port gigabit, PCIe x4. I have read that the Intel Pro/1000's only work with PCIe 1.0, and do not work with more modern systems using 2.0 or 3.0. I do see the HP NC382T, which uses the Broadcom 5709 chip, available for quite inexpensive. Does anyone know if these will work in building a home server?
