I did think about mounting the fan on the bottom and using it as a air intake to cool the HDD's. I've decided I just do 2x 50mm fans in a push / pull one each per side. Should be enough cooling to keep the inside from getting too hot. HDD is gonna be SSD so heat shouldn't be an issue. Hope to lay the paint and paxmate tomorrow, along with a bit more braiding and maybe a start in etching if I can find my transparency film.
