The computer arrived within 5 days - very good. I took pictures of everything - box-PC etc. All in very good shape no dents, scratches etc. Dell Workstation came with Windows 10 Pro - included upgrade to Windows 11 ( Home or Pro?) Load Belarc Advisor and you will find out...Windows 11 Pro - CPU as stated - RAM as stated - WI-FI  USB included - SSD as stated. The only "problem" was a missing DVD Rewriter - NO problem as a call to Tek Refurbs corrected this. Companies should encourage their employees to give a name since now I can thank Lindsy and Bob for doing a great customer service. The DVD was mailed out the day of the call and arrived (after a Holiday) a day later - perfect! Today, customer reviews are a real problem - as I told Lindsy, the company VIPs need to check what is being placed on the Internet. If their have been past problems those comments need to be corrected.  I seem to have a very good deal - time will tell.
