If this is for gaming you really dont need 2011 and SB-E CPU its pointless overkill and with the cash for just that board and CPU you could actually build a respectable gaming rig on 1155 with IB or SB
but as they are 2011 socket i dont know if RAM, Harddrive, etc etc will work with them !!
The CPU and Motherboard which you wish to buy will definitely work with your RAM, HDD and other components. The PC which you have currently supports only DDR3 RAM which means that the RAM you have will work on the motherboard you are going to buy as the new motherboard also supports DDR3. As for the HDD, both the motherboards are on same SATA interface so the HDD you have will work with the new motherboard.
But the main problem is that you have a Mid-Tower Case and the motherboard you're going to buy needs a Full Tower Case to fit in.
