Dell Studio 15, Good Or Bad?

please tell me the pros and cons, should i bother customizing it? and should i get the 17 instead? i want to use this as a pretty general computer but i also want to be able to run a few games on it without slowing down much. please, noone just post that dell sucks, if you are gonna say that tell me WHY they suck so bad ( i know the customer suppert is shity)
i big part of why i want this laptop is because of the really cool chasis design. i know that sounds stupid, but the actual computer itself doesnt sound too bad either, but if you know if it is possible to buy a better dell computer and buy an empty dell chasis and put that on please say so.
