UPDATE 2: The seller told me they would not honor their warranty because they were located in Canada and Hawaii was not part of the United States.  Whatever.  Amazon customer service intervened and although the seller wouldn't budge, Amazon did fix the failed memory problem.  I've been using the computer daily for 2 years since.UPDATE:  One of the "Sesame" memory modules failed.  Waiting to hear back from seller on how this is going to get fixed.  Computer won't even start with defective module installed.Since listings can can change but the reviews stay the same, this review is specifically for:Dell Optiplex 7010 Business Desktop Computer (Intel Quad Core i5-3470 3.2GHz, 16GB RAM, 2TB HDDThe actual CPU installed is a 3550 which is an upgrade to the advertised processor.  The HDD has 57,000 hours on it which is the equivalent of running continuously 24 hours a day 7 days a week for over 6.5 years.  If you use your computer 2 hours per day you would have to use it for 78 years to accumulate as much usage on the hard drive.  I'm not saying 57,000 hours on a HDD is excessive I'm just putting this into perspective that this is not a "new" HD nor is it particularly speedy.  This isn't an issue for me because I'm using an SDD in the machine and it runs very fast with it.The memory was installed incorrectly- in single channel mode.  It works in this manner just far below expectations.  I removed one of the memory sticks and put it in the next slot over to make the memory dual mode and it benched twice as fast.  I've never heard of "Sesame" memory before and can find little about it on the internet.  But I posted a shot of the specs as well.  Cheap memory is usually the culprit in any computer problem so it's something to keep an eye on.  If anybody knows anything about sesame memory feel free to post as a followup comment.Unit arrived looking and smelling new inside and out.
