jesus, how many people have to make smart ass remarks and clog threads opened with legitimate questions? I'd much rather answer this question for 100 honest, curious people than read you're drivel.

Building a bike ground up or converting a road bike is an experience. Most people end up spending more money than they intend to, and many of them swap the parts to a different frame in short order. Granted, as was suggested, you will learn a lot about working on bikes but may become discouraged. If you are not looking to spend much, your best of both worlds may be to buy a bikes direct bike (ie. kilo tt) and a tube of phil grease and some tools and in short order tear the bike down to components and re assemble it.
