This is the 2ND machine I've purchased from JSM Computers out of Oklahoma. The first was purchased in 2016 and finally kicked the bucket this year. I specifically wanted a machine from them. YOU MUST PAY ATTENTION TO THE "SOLD BY." The description remains the same, but since I purchased this machine last week, the SOLD BY has changed THREE TIMES to companies with worse business ratings. I checked this because I was recommending the unit to some friends, and wanted to make sure they purchased from JSM.The pre-purchase response was EXCELLENT with same day and late business hours answers to questions. When I booted the machine and tested the USB ports, a few weren't accepting wired Keyboard and Mouse. I let JSM know and Mark responded very quickly. I was still testing, but I wanted him to be apprised of the situation. I do NOT waste time with the Amazon support. Their solution to any crisis is pack it up and send it back. Instead, I kept testing and after some WIFI and BLUETOOTH adapters were inserted, the supposedly dead USB ports worked, and with the wired mouse and keyboard.The PC came clean... you could not tell how old is is unless you know computers. No noticeable wear or damage. They send a WIFI adapter, and I plugged that in, hooked up the monitor I already had, and it popped up easy as toast. Needed a bluetooth adapter, and once that came, accepted it (TP Link 5.0) without any issues. Did some bluetooth searches for speakers (you will need better speakers) and it found the  Oontz Angle 3 and Tozo6 earbuds, without any issues. It's also found my TV, Roku stick, and something I don't know what it is (should probably find out).The machine is fast. Programs pop up fast, downloads are fast, and when I type, it's immediately responsive. Can't say anything about gaming unless you want to talk Angry Birds friends or Solitaire, but for productivity, online browsing, running applications like Scrivener, Libreoffice... It's a great machine for  under $200 (I purchased a 3 year protection plan just because which made it $200.) Now if I have issues with it, I'll update this review, so if you don't see any update, it's doing just great.Remember JSM computers sold me this machine and provided pre-purchase support, actually on another two machines, and I ended buying this one.  Oh! and I was informed by Mark that the Microsoft Certification that came as a sticker on my last machine is now built into the computer memory/hard drive? and recognized when you go online. I notice a number of reviewers doubting authenticity of software because they didn't see a sticker.Dell Optiplex 7010 Desktop Computer - Intel Core i7 Up to 3.8GHz Max Turbo Frequency, 16GB DDR3, New 1TB SSD, Windows 10 Pro 64-Bit, WiFi, USB 3.0, DVDRW, 2X Display Port (Renewed) - Excellent Condition. $180.11.
