The first CM6870-US-2AA I received wouldn't boot properly & went into an endless loop, so after several frustrating hours with Asus tech support, I had to take it back. Once I got the replacement, however, the 2nd one worked like a charm. I initially bought this to replace a very nice Dell that I lost due to a house fire. The Asus seemed to offer the biggest bang for the buck that I could find (and afford), so I went for it. I'm glad I did, in spite of the initial Window's installation problem.

Most importantly for me, this little baby cooks right along. In my purely subjective opinion, it even seems to smoke the Dell that I had, which cost at least $400 more than the Asus Essentio. The Asus keyboard is also of a better quality than that which came with the more expensive Dell. The bottom line is, I don't think you're going to find too many desktops right now that offer as much for the money as this one. I mean, come on: 12GB of ram; a 2TB hard drive; a 3.1Ghz Core-i5 processor; and an Nvidia GeForce GT-520 1GB graphics card. For this price? But again, here's the real deal for me: the performance. No, I haven't clocked it, but I certainly can see and feel the performance and it is doing just great. I do high-end 3D graphics work and I was afraid that the GT-520 would be too wimpy for my work, but so far it's holding it's own quite well. Time will tell on that score, however. Now I admit, I'm not a gamer so I can't speak to that. But I would hazard a guess that this machine just might do quite well with that as well. If not, one could always upgrade the graphics card and probably still come out ahead in terms of price.

I bought this machine to replace a very old, very solid machine which I had built to spec by Micron (which, alas, is no longer an option). That machine served me well for 10-15 years until it was brought down by an onslaught of network attacks. In brief, a friend got hacked, my info was in her contact list, and I got attacked (note I was running 2 firewalls: hard & soft,) Kaspersky and windows defender. They were determined! After a month of trying to wrangle my machine into shape, I bought a new one... after considerable research (an understatement).
Because I had not intended to buy a new computer now, or budgeted for it... this was rather an "emergency purchase". That said, I did not get the machine I might have had it been approached differently (which would have cost circa ($3000-4000).
While not an engineer, I am not a novice either, having played with computers since the early 1970s (starting with a DEC PDP-10). I have purchased a few desktops since that time, and those experiences led me to rule out HP, Dell and IBM as reasonable options. (Those experiences are too extensive to to detail in a review of another product, but suffice it to say that I would not buy a post-it note from HP, and am not much fonder of the other 2). The companies at the top of my list have moved on, and so I began by 1: ruling out and 2: using more recent experience with other equipment. A few years back I bought a net book, again, after much research ;) and determined that the most solid equipment was made by asus and MSI. I have been very happy with my little ASUS machine, and have since bought 2 monitors from them both of which are very solid, (and were exceptional values besting a Samsung which cost 5x as much).

What I was looking for:
1: fast.

I am 57 and have owned most every brand of computer.
I am an engineer and amateur astronomer and task my
computers very heavily. This one does it all with ease.
Thankfully I got it before windows 8!

There's nothing I don't like about this computer. It's quiet, has lots of USB ports (4 of them right on the front), and slots to read 3 different camera card sizes. It has all the power and memory an at-home user should need.

I was a bit leery when I purchased this computer because I have never purchased a 'refurbished' computer before. But I have to say this computer is very impressive. The OS came pre-installed (which was handy) so all I had to do was plug in my monitor, mouse, and keyboard and I was off and running. The only drawback to that, which others have mentioned here, is that you do not have an OEM install disc should you ever need to re-install the OS. The keyboard and mouse that come with this computer are just your standard, run-of-the-mill peripherals but they are definitely serviceable and will easily get the job done. As with most desktop computers, you will need to purchase a monitor separately. I purchased an Asus 40" LCD widescreen monitor and didn't even need to do anything. I just plugged it in and the computer automatically set up the display settings to maximize the monitor. The only issue I have run across with this computer was that it came pre-installed with VLC Player and three movies for that program (Ironman 2, The Amazing Spiderman, and Men In Black 3). Ironman played all the way through, MIB3 packs in about 20 minutes in, and Spiderman wouldn't play at all. But I consider this an insignificant issue because I bought this computer for other reasons, in which it performs admirably well. The only thing that would make this computer better would be some rubber feet because the bottom has a protuberance that makes the tower ever so slightly wobbly, but not enough to cause concern or issues of any kind.
