I want to build a new home office server running for my business. We want to run MS SBS 2003 on a setup that use RAID 5, dual NIC, 3 x 250 GB HDD and about 4 GB RAM. However, I am not sure what to do about a motherboard. I don't know whether to opt for a specific server motherboard or a normal desktop one. Any advice would be much appreciated. I've budgeted about $1500 for the server. Many thanks.
