As you add more and more addins to your Windows Home Server you may find that it needs a memory upgrade and for self-built boxes that is easy to do but for HP MediaSmart customers adding memory would void the warranty but today HP announced that they are changing the warranty policy to enable existing and future customers to upgrade their MediaSmart servers without voiding the warranty

Details from HP:

HP customers can now upgrade the memory on HP MediaSmart Servers without voiding the HP warranty.

Based on customer feedback, HP will now offer a path for consumers to upgrade the memory on the HP MediaSmart Server without voiding the hardware warranty. HP customer feedback and research shows that some customers are installing multiple add-ins and/or additional software to the MediaSmart Server, which can lead to a need for additional memory.

Details

Upgrading the memory, in and of itself, will not void the warranty on the MediaSmart Server.  Damage to any part of the MediaSmart Server during the upgrade may violate the warranty, however, leaving the cost for repairs the responsibility of the customer.  Customers should perform a backup to an external device before adding additional memory.

HP is only providing information on a customer memory upgrade path at this time, and customers will not be able to send their MediaSmart Server to HP to perform the upgrade. Customers may be able to find technical assistance for the memory upgrade, however HP is not recommending or training authorized resellers to conduct the memory upgrade on a MediaSmart Server.  HP has not qualified any particular DIMMs, but compatible memory includes 1GB or 2GB – DDR2 667 MHz DIMMs.  Customers should not upgrade beyond 2 GB of memory. Other than disk drives, HP does not support any other hardware upgrade paths, such as processor upgrades, on the MediaSmart Server.
