mikinhoBased on your feedback I would go w/ WHS 2011.
In terms of your motherboard…do you want low power consumption? My current home server is a dual CPU AMD Opteron (G34) Supermicro system. That is overkill for most people but I really like the system and they have a good single CPU board: H8SCM-F.
What I like about it…1- six cores at an affordable price; 2- dual Intel network cards; 3- PCIe x4 slots…hate not having anything but a single x16 and x1 slots; 4- IPMI 2.0….being able to connect to the console and turn it onoff over TCPIP has saved my butt a few times.
If you want low power than an Intel Core i3 makes for a good home server. Just make sure to get a board with an Intel network card. See Andrew’s guide, Installing a Server OS in Intel Media Series Motherboards, for more information using an Intel Media Series board.
