Well I spent over 2k on a 3XS system within a month had to be returned to them since it kept crashing , found out they had overdone the OC fast forward a few months and low and behold component failure . so this time I had to remove it and return it to scan . Number 3 all case fans failed . so had to send it back said ti was repaired then failed in Quality control then finally passed . Received it back in a flimsy box where even though it was wrapped in bubble wrap it moved considerably in the box , yup failed die to someones incompetence in scan yet again . so back to them again for them to sort it out however if I knew what I do now I would not touch them with a barge pole.
