Sata connecter came away my motherboard at first attempt. rendering MB useless! So far CCL have refused any responsibility or to address this issue in any meaningful way. I am waiting for Christmas to pass before following up on my consumer rights. I shall not deal with this company again (CCL) I have replaced the MB from another vendor. I can confirm the CPU and DRAM are very quick and quite impressive I can only recommend potential purchasers to look around first CCL have a VERY poor customer services to handle anyting that goes wrong.
