Dell makes a good reliable computer, so purchasing one of these renewed computers is a good bet.  These computers have 6th or 7th generation Intel processors, but it does not matter, they are still very useful as a general purpose computer.  Since they are renewed, expect some blemishes, but normally the blemishes are not severe.  Occasionally, something is broken such as a USB port or the computer is configured incorrectly.  No worries, the seller will correct to problem right away.  Just a minor nuisance.  I have purchased several of these for my home and office.  The only thing I do before putting them into service is replace the thermal compound on the processor.  You don't have to do this, but it helps the processor run cooler, and makes the computer last even longer for more value.  If you're going to play hard core games with one of these computers, make sure to get to full size desktop case.  The SFF and micro size cases will not fit a full size video card.
