Plus you'll get more bang for your buck building a system yourself (assuming you have at least $500-$600+ bucks), less crapware on your system, you can spend money on the parts that will do the most for your needs, rather than get a machine designed for a homogenized "consumer" that is assumed to spend 90% of its time on Facebook or Excel.
Plus there's the great satisfaction of having made something useful yourself with your own two hands rather than getting something assembled in a sweatshop in China... Even if most of the parts were made in China anyway.
There you go.
Also, unless you're a total klutz, the finished product will look much, much nicer than a pre-built generic Dell tower. Especially from the inside.
As far as cost goes, the more powerful the system, the cheaper it is to build it yourself. Dell, HP, etc are only cost-competitive with custom building at the lower-end specs.
