I've been building my own computers for 30 years, back to the era of 286 processors.  A solid state system lasts forever - in the Mojave desert.  Not so long in Hawaii, where the humidity and salt air mess with delicate electronics.  I had a crash in a ten year old LG1155 setup , and bought what I thought were appropriate replacement parts, only to discover that a 9 month old power supply failed.  This HP system has better components in all respects except built in storage, but it has lots of USB 3 ports for external SSD's.  If you bought the components for this system separately, used, in a competitive market, you'd spend nearly $1000.  The OS alone is a major expense, and installation is time consuming.  I wish I knew about the availability of refurbs like this years ago.  With the 90 day warranty, you can't go wrong, the computer will work as it should or not.  I am ecstatic, because I could not get any work done while I waited, and now I'm in control.  Thank You!!!
