I thought I’d made a huge discovery back in April when I bought this perfect little certified refurbished Dell Optiplex for less than $300.  The following is my email to the seller today (if Amazon allows it).I know I’m too far beyond your 30-day warranty policy.  Whether you decide I deserve anything more than an apology is up to you.However, I have had nothing but problems with this machine.  I think you’ll have a record or log of calls beginning fairly early, resulting in my having to replace the guts of this stupid machine at a cost of several more hundred dollars.  When problems continued, everybody got involved - Best Buy Geek Squad, Microsoft, Apple, AT&T, all of the above with their own charges for time, labor, and equipment.As of today, it’s of no use to me.  It can’t be “fixed” anymore.  Why?  Because I don’t have enough money to pay for my electricity - one result of an inability to work and actually earn money instead of throw it away.That’s all.  I’ll be posting this as a review also - negative, I imagine you can guess.
