I'm interested in purchasing a laptop from my local Microcenter. They've got an MSI GT70 0ND-444US for around $750, which seems like quite a deal. The caveat is that it's an open box item. Is this a bad idea? I don't want to end up with an expensive paperweight. The product comes with a 15-day return policy, which allows me to return it for any reason for the full purchase price. It also has a one year manufacturers warranty, which can be extended. Thoughts?
