Hello Krisrichard. If you have the necessary skills, you can install this expansion card in your PC without any problems. According to Digitec specifications, your PC should still have 3 PCI-Express x1 slots free. You can find instructions on the Internet, and you should not need more than a Phillips screwdriver.
In rare cases, the slots could be covered by other parts of the PC. I do not expect this to happen. If you want to be sure, take a quick look first.
