Bad news is, after 7 months the tower just didn't turn on one morning - good news is, I called the company, CNB Computers, that did the initial refurbishing and they couldn't have been nicer - I did have to pay $55 to send it back through FedEx, but it's cheaper than having to replace the entire tower and start all over again - I had purchased an extended warranty through Amazon, but because it was still under warranty through CNB, I had to send it back to them and give them a chance to fix it or replace it firstI was kept in touch by email with one of their reps that they received the computer and it would be about 3 days to know the problem - in 2 days I was told it was fixed and no data was lost, so I got my original hard drive back, which was a big plus - they shipped it back immediately after that, provided the tracking number, and I've been using it just fine for the past week, fingers crossed - the whole process took about a month, but that was mostly because I am in Hawaii and this shipped to New York cityThey also sent along a new power cord for the computer, a keyboard, mouse and wireless USB, all at no charge - I am currently using the keyboard and mouse on my MacBook, so I can't complain too much - luckily, I had my MacBook to use through this whole process but it was still a huge inconvenience to be without my desktop computer and the information it contained for a month - I am glad it all worked out the way it did, and grateful to the people at CNB for all their help, but I don't think I will purchase a refurbished computer again - by total contrast, a few years back, I had bought a new HP directly from HP - when it suddenly died one day under warranty, they overnighted a new tower to me at no charge - you get what you pay for
