Do you want to get a SSD (Solid State Drive), or a 7200RPM for the Boot Drive?
Solid State Drives are much faster at reading data than mechanical hard drives are, but are more expensive per GB.
Most people including myself usually have a small SSD drive as the boot drive (this is the drive your O.S. is on) and another hard drive for extra data storage.
Lastly, adding the cost for Windows 7 or 8, usually adds another ~$100 to the cost of a PC, is that also a cost in your build?
