sorry I miss read the model as I 3650.  i5675 has a depth of 437.53 mm (17.23 in).  By the look of it inside it should be able to take a long card such as RTX3080 which is 11.2" (285 mm).  You should have plenty of physical space. In the link below the card is AMD Radeon RX570 which is 9.5”. RTX3080 installed would be 1.7” longer than that. [URL]
hey guys, just asking a quick question, im really thinking about upgrading to an rtx 3080, ive done some measurements with a ruler (idk if its accurate) and ive seen that theres enough space for the 3080, currently i have an rx 580 8gb, ive also upgraded to a 700w psu, can i get some info on this?   tl;dr can an rtx 3080 (285 mm) fit into an inspiron 5675
would an rtx 3080 fit into an inspiron 5675?
