Purchased for school. Upon initial start up, immediately after unboxing, I was met with a “fan error” message. Connections were checked. Device was restarted. Still an error. Ran a systems diagnostics check - processor fan is inactive. Will need replacing (over $100 according to the searches I’ve done). Very disappointed. Glad I got a warranty =\**UPDATE**Sunset Micro promptly contacted me after learning of my experience. Arrangements were made to return the tower for an exchange. My new tower came within days (4 or so?) and is working perfectly. Exterior has some scuffs/dents but it’s a refurb so this isn’t a dealbreaker or unexpected. Worth the price point and the customer service was great.
