Lenovo Ideacenter Seal?!

[GordonD]

I have a Lenovo IdeaCenter K200. Its got 512MB RAM and a 250GB HDD with Core2Duo Processor. I'd like to upgrade the RAM, but is it okay to remove a seal thats present on the PC cabinet?! Will it void warranty?! PLEASE reply ONLY if you are very sure of your answer.

Moreover, is it possible to install a graphics card into this PC?!

Thanks in advance
Gordon.

well i have the same pc i already opened the seal and replaced the ram to 2 gb and bought a new msi 9600gt 512mb graphics card and well it works but you need to upgrade your power supply to 500 watts.
