"Most power for the least money..."3.5 starson by Scott7000
Pros: Lots of memory, good storage, first generation i5, lots and lots of USB ports, easy to access memory card reader.
Cons: Underpowered graphics; keyboard isn't great. For "green" reasons, it has a rather low-powered power supply; this might cause the hardware/BSOD problems that others have pointed out.
Summary: Like others, my system BSOD'ed within hours. Mine was a refurb, so I didn't feel any hesitance in opening the box (as the seal was already broken) when trying to resolve the problems. I would say that Asus customer service was pretty good--if you have another computer and can fill in an online form to get a priority number first. With the priority number, I never actually had to wait to talk to a human being at Asus.
After trying to re-install the OS a few times, I ran memory tests and got hardware errors. As with some of the other posters, I sent the unit back to Asus, got it back in a little less than three weeks, with a printout saying all they had done was re-install Windows. This wasn't accurate, as my unit initially came with a Hitachi HDD, and it came back with a Seagate, so they obviously did more than reinstall the OS. I'm not sure what else they did--perhaps replaced the memory, too. I may open it up to see if they beefed up the power supply...
I've had the unit back for a week, with no problems, and while I'm not gaming, I'm not going too easy on it, either (I'm using it as a home Pro Tools system, and I'm also using it for InDesign).
And I think this is the underlying problem--if you, for example, put in nearly any modern video card, plus hook up a number of powered USB devices, you might overtax the 300W power supply, possibly causing the BSOD-causing hardware problems.
