As I said in my thread about the install it is my intention to extend the onsite service contract for my new system just as in the event of anything going wrong its easier to get it fixed onsite than having it returned to Scan.
My question is, if I decide to add something such as an SSD or to upgrade the graphics card in 18 months would that void the warranty or would it be ok provided I bought the parts from Scan and discussed the issue with technical support beforehand?
