Frequently asked questions
Can I swap out parts and/or add/change/remove operating systems in a KW Tech PC?
We can add any part to a PC for a small fee as long as we don't need to remove an existing part for it to fit, for example adding more RAM, an extra hard drive, installing a Windows OS, or adding a graphics card to a PC without one (we can even SLI/Crossfire for you if it is compatible). We cannot change components that are part of an existing build e.g. Upgrade an existing graphics card or add a SSD with Windows installed if the PC only has a single hard drive (as the OS is already pre-installed). If you do have a specific requirement, then one of our experienced sales team will be happy to build a system that suits your needs.
