So i'm having this question. Can I upgrade my prebuilt pc (Acer aspire XC-705) with a new case (Deepcool TESSERACT SW-BK), PSU (SeaSonic G 550W 80+ gold semi-modular ATX) and a GPU (Gigabyte NVidia GeForce GTX 760 WINDFORCE 2x OC 2gb)? Mainly I'd like to know that are the old parts compatible with the new case.
