I bought this computer to just record security cameras running Blue Iris.  This computer essentially replaces an NVR recorder and costs only slightly more than an NVR.  The benefit is that the computer is far more flexible and allows your to do more with your security cameras.  The computer is outstanding with only two small scuff marks on the case which are not apparent unless you look.  The computer was absolutely clean inside and out with just no signs of wear.  I replaced the second 500GB HDD with a 6TB purple drive.  I've waited for a couple of weeks before providing a review to ensure there were no issues with the computer.... and there is none.  It booted up without a problem and is wonderfully fast and quiet.  Security cameras can really hog CPU and RAM and I've had no issue even while processing videos.  My old computer could chug through video editing but it was just so slow.  This one with its i7 quad core and 16GB of RAM blazes through the process.
