how many PCs are you connecting? building a switch into a PC means the rest of the machines won't have a LAN unless that one PC is on and its OS is specifically configured to forward frames between specific interfaces. this might also put a strain on the OS, since it will have to forward frames for other hosts on top of processing them for itself. i'd say just get a 5 port gigabit switch and call it a day. it will get the job done perfectly and cost next to nothing.
