Right now, you've got two bikes you can't ride. I say go for it, build up one you can ride.
Absolutely and, guess what, you will still have a lovely, though purple, frame to sell. And, keep in mind that lots or people prefer to start with just a frame/fork st and then build the bike the way that they want it.
With that in mind, you should be riding the white bike later today. Best of luck.
