I have had good luck with ASUS "pro" series motherboards. The price/features balance seems about right with them in my opinion.
As for hard drives, for a system in the $1500 range you might as well go with an SSD for the boot drive. Get a Samsung 840 EVO in 500GB or 1TB size for your boot drive and a secondary 7200 rpm drive for data, and use the properties menu option to move your "my documents" over to the 7200 rpm data drive. I like western digital black drives for price and performance and, for me at least, reliability.
