Yup, no problem. That seems to be one of the things a lot of people overlook when building a box full of blower cards. They end up with poor case inflow and an overall negative pressure. Then their cards have to keep ramping up to try and cope with the lack of fresh air. You want to at least balance the air inflow vs outflow, and maybe lean a bit towards the inflow so you end up with an overall slightly positive pressure in the case. This will keep the cards fed with fresh air and can also help to keep dust and stuff out, assuming your intakes are all filtered.
