I stumbled onto your chat about the R2 and I humbly present my review of it:

I completely understand it may not be a great choice for those of us who want the latest and greatest, but I get where Alienware is coming from with its Alpha. The R1 was a good start, but it could barely run most AAA games.
With the R2, they've improved its hard drive, its RAM support, CPU, and its GPU received a HUGE overhaul when compared to R1. For those looking for a small, form-factor PC to go in their living room, dorm room, or bedroom, this is a great option.
I spent two weeks with the Alpha R2, and I used it every single day. So if you have any questions, I'd be more than happy to answer them.
