I needed to equip another office space as my company is growing. This will be my 4th purhase of this computer with same spec. The others work flawlesly.  I ordered this one from Amazon Prime supplied by ConfigureSystem. Became aware quickly there were some issues. One of the folding feet on the keyboard was missing. Not A big deal. After unboxing the rest, there was no  paperwork, ID, Service Tag info or even a Thank you. There was a small Service tag# on the computer. The other three computers were complete with basic information and contact info. After setup I found the CD unit would not open. I removed and reinserted the cd unit and it works, but is noisy..After installing Crystal disk info, found the SSD at 43%. My first 3 optiplexs were in the high nineties. I replaced the SSD with a Samsung EVO.E Mailed ConfigureSystem with no response.I could have returned the unit under prime free returns, but needed to get the 4th unit operational.Lesson learned. Next time I will purchase from suppliers I have had success with.
