Always check the "Fine Print" of the warranty. If anything seems too good to be true, it usually is. Make sure that the company will give you a loaner part if yours needs repairs. Be skeptical of companies that put "Warranty Stickers" on their cases restricting your entry. What are they trying to hide? Also, be aware that many of the components in a system are covered for longer than the system warranty period, as long as they are quality systems. Always be sure to ask about the details of the individual warranties on parts being used to see if they are longer than the complete system warranty. Finally, be wary of warranties on peripherals - they can trip you up very easily. Make sure your chosen supplier has very clearly stated warranty policies with regards to handling of hardware AND software problems. Be sure to ask what level of service you wil be provided with if you need to make a warranty claim.
