I bought two of these computers. After few months of use both start laud noise and later and warning about crush and losing data. Please note that both computers setup in clean office and more space for air circulation and no danger of over heating.The first one was within warranty period and HP fixed it for free but the second one I paid 235 dollars that's over 60 percent of the purchase price. Since it was my server, I didn't want to take risk. So be careful guys.
