I've only had the PC for a month so I can't remark about its longevity.  Works like a normal PC should.  I like the smaller footprint and have my monitor sitting on it.  Since the power supply is in the cord, similar to a laptop, you don't hear the fan from a power supply.  The only odd thing to me is they put the headphone jack in the front of the box.  If you use this jack for your external speakers, then you have at least one cord sticking out the front while all the other cords are coming out the back.  I prefer having the 256GB SSD to help with the speed of loading and unloading software, reboots, etc.  Has plenty of space to hold Windows, Office and other apps with room to spare.  I have a similar model I use at work and have been pleased with its performance.
