What case is it? Do you like it? Does it suit its purpose? What build will you do in it?
Talking of which I have a few cases sitting around I guess should get rid of, Silverstone, Antecs, Coolermaster
Hi, reg airflow and GPU, I think it should be fine, I see two fans screwed to the inside of side pannel but will keep all that in mindDepending on the models and condition they could still be worth some money, especially for retro builds
Regards your original question, it may well be fine, the biggest problem with older cases is generally lack of airflow and GPU space, but this is obviously very dependent on what case it is and what build you want to do in it.
