What RobbieTunes is trying to say (I think) is that we can't really judge costs for you. It is usually cheaper to find a complete bike than to assemble a bike from pieces. However if you buy a complete bike it may have a few things that aren't as good as they could be. You can always upgrade individual components later as your budget allows. All this should be obvious.
Assembling a bike from components and a good frame will usually get you a better bike. 105 components are good. Finding a good frame requires patience and knowing what you are looking for.
