You're not out of touch. I would consider this a mid-range gaming PC for
today's games. It's not low-end. My 9 year old PC at home with the AGP v1 video card, the missing side panel, and the box fan blowing into the case (which barely lets me run through Orgrimmar on low settings) is a low-end gaming PC.
I looked at the PCMag review, couldn't get to the IGN one from work since it's a "Games" site.
The GTX 545 / 555 slightly worries me from the driver support standpoint (since they are OEM off-models), but if it's really a watered down 550/560 like Google tells me then it's probably the best thing the PC has going for it, gaming-wise.
Looking at the pictures
here, it looks like it is not the clamshell case of my past Dell nightmares. It looks like everything is in removable cages, but it still looks like a giant PITA to work with. (I guess that'll be a flaw of any mini case?) I just don't understand how the thing is "tinker-friendly" like they imply in that review. Since you can't significantly upgrade most of the components, what's the purpose in tinkering? Yes, it's got an Intel 1155 socket and you can upgrade the CPU someday, but that applies to just about any new PC.
I'm just saying once you buy it, you're pretty much set and stuck with it as-is, performance-wise. You don't have support for the two best upgrade paths for a gaming PC - the most economical way (overclocking), and the most-bang-for-your-buck way (new video card). If the mini case is a real advantage for you, then go for it. If that's not the dealbreaker, why not go with something in a bigger case with a standard ATX motherboard? At least then you could upgrade the bottlenecks (in this instance: power supply and airflow) someday for relatively small cash investments.
Yes, I would personally be ashamed to own a desktop with an Alienware logo on it, but I'm willing to look past that. Even with a relatively objective view, I can't see this being a good purchase (for me). If I were living in a crowded dorm room, a gaming laptop would probably be a better choice. If I were in some sort of hospital, maybe a children's hospital, where we had to bring it from room to room, I'd still probably go gaming laptop, with a docking station in each room (so I could swap keyboards once they get all infected or whatever). Maybe if I were setting up a public kids recreation room like at an airport or at a restaurant, and I could lock it down in a cage, and if I only had 700 bucks worth of funding every couple years?
I'm not trying to put this PC down. I figured you were trying to get opinions of other folks around here, and this is mine.
