Just went shopping on newegg, and for price of a "Level 1", you can get same Mobo/CPU/ram, a bigger PSU, same SSD, a blu-ray instead of crappy dvd drive, corsair 800D fulltower case and THREE 580 GTX 3GB models w/ watercooling block.
Throw in a $300-$400 watercooling setup to cool all the GPUs and CPU and you got yourself a completely watercooled system that would perform at the same speeds of a "Digital storm lvl 4", for about half the price lol.
Well, if you got the money and can't do the work yourself, sweet systems I guess lol.
