Yep. Especially when you have many devices. Server can handle it easily. It's just some people are using Win 7 Pro as their servers. I don't recommend using ICS to use that "main" computer as a DHCP server. Also another thing, you might want to get a patch panel with that switch if you're wiring it yourself. May even want to consider CAT 6A cable which is much more expensive but is rated for 10 gigabit connections. Would be good if you're running many wires through a building for example assuming you have the money. Anything above Cat 6A and might as well get fiber, but be advised, setting up fiber is more difficult and costly than standard Ethernet cable.

CAT 5E - Standard
CAT 6 - Above Average
CAT 6A - Future Proofing
Fiber - What are you running a data center?
