I ordered a Predator desktop direct from Acer and was looking forward to using it, since the reviews were great and I've ordered a few Acer products before.
The computer arrived to me nonfunctional, making a loud whining noise when turned on. I attempted on my own to reseat the RAM and reconnect all the components but it did not resolve the issue. Neither did calls to Acer. I requested to return the product as it was defective, however while Acer refunded the cost of the product, they would not refund the significant ($200) shipping cost of returning it to them.
Seriously the worst customer service I've gotten from a large company. Would recommend against ordering through Acer if you choose to buy at all, or better yet, just build your own.
