3 years ago i got a dell inspiron 3670 and i put a graphics card in and that was it. Over the last year i have switched out multiple parts such as the HHD to an m.2 SSD, cpu and cpu cooler. Is it possible change every other part(PSU, mobo and case)? Beucase I have been thinking of getting a new graphics card and for that i will need a new mobo and then I will probs need a new psu so it it worth it just to change every part? Thanks
