IMO incorrect. Simple research shows that they were founded as a small independent company in 1996. There were not acquired by Dell until 2006, meaning they had established themselves and their independent designs for 10 years on their own. According to the article below they still do their own design work.
Recently I looked at both Alienware and Dell notebooks and they are quite different from one another. What I saw was that all the Dells were just not quite up to par (for SketchUp) in the 1000-1600 price range, and the Alienware machines were but were a bit over priced compared to other “gaming machines”.
The finalists were an Alienware and an MSI notebook, and when the MSI Leopard 8RE went on sale at Walmart website for 200 dollars off, that decided me, as it basically paid the sales tax and an upgrade to Windows Pro.
The Alienware will allow an upgrade (or come with Win Pro depending upon model,) but in my case I’ll have to handle the upgrade to Windows Pro myself via Microsoft’s upgrade portal. I advise you to upgrade to Windows Pro as it will give you better update control as well as other professional features and it is only 70 bucks extra.
Lastly, I suggest searching YouTube for inspection videos of the model machine you are interested in. There are techs that post inspection vids for many many machines. Quite interesting, and you get their informed opinion on upgrading, access to components, setup, overclocking, etc.
