If you add up all the costs for parts, tools, time and labor, I can't see it coming to that much less really. Plus, the final product won't be as clean as the professionally built unit. And you can't beat having the final product delivered fully assembled to your door. The individual components cost a fortune too... Just my 2 sents. I'm poor as hell, but don't mind spending money on something that's an investment...

This pre-built unit looks really REALLY NICE!!
