I came across bufferstock by chance as i required a PC with twin screens and twin drives. John was quick to reply to my emails and helped me select a PC package and confirmed stock. The Dell Optiplex PC system i purchased is superb, in excellent condition and runs like new with Windows 10. There was no evidence of previous files, accounts or logins…PC was nice and clean. The Wifi flys, all cables were included, new keyboard and mouse and with twin 24″ Dell screens is great for more productive work. The PC was well packaged and delivered within 7 days over a holiday period! Excellent service, PC system and price. Thank you!
