Hello All! I need some advice. I am looking to get a PC to run my 3Dsoftware, SolidWorks and Alias Studiotool 12. Thats all it is going to do. I have my Macs for the rest. However I would like some portability too. That's why I tought of the Alienware Desktop replacement laptop. They have a $500 instant rebate on their 17" model. Do anyone of you know anything about these machines? Or do you guys have any other suggestions? Thanks!
