I purchased a used sytem from these guys ( fsyb1080 Precision PFL, Inc.)and they give a 60 day warranty. Two days after 60 days I got an E74 error. Microsoft wouldnt fix it because they had already voided the warranty and they wanted to sell my a repair service just to fix it. I took it to another repair company and they said that it was repaired with a temporary fix only. Seems very shady to me and I lost $180!!! BEWARE BEWARE BEWARE!!!
