I purchased a Dell Optiplex 7010 from SkyTech USA LLC (fulfilled by Amazon), just a little over a year ago. I've used Dell computers in all the offices I've ever worked in and wanted one for my home office as well. I was a little hesitant to purchase a refurbished computer because I'm not very technically oriented, but decided to try it out since it just seemed to present a much better value than buying new.I was pleasantly surprised to encounter minimal issues during the setup of the computer when it arrived. The included Windows key functioned without any issues and I was able to start working on it shortly thereafter (installed a separately purchased Microsoft Office suite as well). I have pretty basic computing needs -- documents, spreadsheet and web browsing -- so there's not much to judge the performance of the computer on, but performance wise it's been more than adequate for my needs. The only minor lag I encounter is when viewing large, graphically intensive files like architectural drawings, although I'm not sure if that's to blame on my older version of Acrobat.I would have given this a 5-star review except for one somewhat significant hardware issue: The computer shipped with a worn-down CPU fan. The fan made a grinding noise right out of the box and the seller should have replaced it prior to shipping. I first thought it was a bearing issue but later discovered that the fan casing was slightly warped, which is a common issue for the CPU fan assembly on small form factor Dells. I recently replaced the fan after the grinding noise got to a point where it felt like parts would start flying off the chassis. It wasn't too hard to source a used OEM part online, but I was without my work computer for several days.Overall I think the computer is still an excellent value, but I am somewhat disappointed that the seller didn't replace the CPU fan prior to shipping.
