Upgrades are only available for PCs purchased from The VR Rooom and are compatible with all of our PC systems. Within 48 hours of purchasing an upgrade, a prepaid shipping label will be emailed to you that will need to be printed out and attached to the box that you will be using for shipping. Including transit time, this whole process normally takes about 2 weeks. Please be aware that any upgrade purchased will give you a 3 year parts and labor warranty for that part only. This does not stack on top of your normal system warranty, which will expire 3 years from the system purchase date.
