arrived poorly packed, box was too large and additional styrofoam corners were used to pack box by just randomly putting them on top of box without securing them. PC never worked out of the box. When installed, the Case rattled, so I brought it to a local computer tech and the opened it in front of me to find broken plastic retainers that were not secured when the drives were installed. The tech then showed me an abundant amount of dust built up inside of unit as it was never refurbished, only "repaired".  Also power switch was frozen and would not turn on  found more broken plastic around the faceplate where the switch was located.. Power cord that came with the unit was defective also. Could not contact SKYTECH, never answered phone for two days finally answered and told me I was out of luck, it would take at least 5 days to get a new one. AMAZON did not back up this company, refused to replace it, instead offered a credit and now I'm out since I had to bring it to a store to have it checked out and was totally embarrassed when the tech opened the box. AMAZON couldn't give a damn and SKYTECH is a Canadian company that should be closed for "POOR QUALITY, POOR SERVICE and ZERO TECH SUPPORT. Put your hours of operation on the card-- the only paperwork that came with the unit-- no manual or even an invoice or proof of purchase. POOR POOR POOR negative 10 rating.
