Bought 2 - both run well no problems after 2 months of office work.Both computers arrived on time and very, very  clean inside and out.  Very pleased with TekRefurbs.Read review from Mike "Good Mini PC for price" on 17 July 2020 - says it all.Only disappointment - no TPM header.  It is not listed in the spec sheet, so no surprise but still disappointing.  Not a deal breaker - I'd buy again.
