DO NOT PURCHASE FROM THIS COMPANY!!!!!! I purchased a refurbished tower from them and received it on time but it didn't boot up. After at least 6 phone calls to their customer support, the first 5 weren't answered, I finally got someone who attempted to help me by watching videos on YouTube about the machine I purchased. Ended up sending it back and got a replacement. Hooked up the replacement and same issue. Tried calling 6 times and never spoke to a living person. Finally got it to work myself. Go in the next morning and nothing. I will be sending this back and demanding a full refund. DO NOT BUY FROM THIS COMPANY.  They sell shoddy machines and don't care about their customers. Spend your hard earned money somewhere else
