I bought this Optiplex 9020 for a user needing a small but powerful system where cost reduction was a priority. This system combined with a low-profile GTX 1050 Ti was the perfect fit for what they needed. Refurbished hardware is always something to check and research well, and this seller both provided excellent condition hardware and excellent customer service for a missing wifi adapter; they sent me a bluetooth/wifi combo adapter at no cost to make up for the missing adapter. The end user couldn't be more thrilled!
