If you're handy enough to build up a frame, then get a BD bike. Disassemble it, re-grease and re-torque everything, and true-up the wheels. I think you'll do better cost-wise than trying to build up the Nashbar frame.

I built up a Nashbar CX frame (the older one with 135mm rear spacing). It has Avid BB7's, Mavic 317's with XT hubs, Ultegra drivetrain, Dura Ace barends, Cane Creek SCR 5's, a Brooks B17, etc... I had many parts lying around for the build, but it still ran me more money than buying a complete bike. Even so, I love it.

If cost is a major factor for you, I'd discourage building from a bare frame. If getting exactly what you want is most important, then the frame-up build is the way to go.
