Sorry, my bad. When I opened the Dell Alienware x51 page and the low tier was displayed as the default and went from there.
Still, personally I wouldn't trust any pre-built computer unless it displays the full component list. Motherboard especially is a big thing since it dictates future upgrade paths and is usually where the prebuilt computers skimp at.
The 330 w external PSU is also quite limited. There are more powerful and cheaper internal PSU's that can be used and that provide a better upgrade path. Also depending on how the power is split among the 330W, in some usage scenarios there may be some strain on the PSU reducing it's service life or the system will throw a fault when underpowered under transitory loads. That's one of the reasons why the custom built gaming computers typically go with 600-800W PSU's for single video card configurations when typical system loads don't go above 300-400W.
I may be mean here but to me it looks like the PSU maybe is designed to fail in 2-3 years or so to generate future business.
The non 'k' i7-3770 is put there just to be a eye-catcher with it's "i7" promo behind it. A cheaper i5 'K' series overclocked to over 4Ghz would pass over it at game performance. But of course, that would need a good aftermarket cooler, which I doubt the case can accommodate (heck..they even took out the PSU from the case...).
GTX 660 video card is ok. Will play the latest and greatest games at medium-to-good graphics and should suffice for a couple of years.
All in all it looks like a non-optimized system, with some marketing attached to it. Personally, stay away from the 51.
