Thermal Take shark case mod questions

[Spun Ducky]

I have the older by today's standards thermal take sharkcase I was wondering if anyone had any info on the side panel grill area. I would like to add a fan setup to it but I am not sure entirely on the size of fan(s) to use. I also would be interested if it would be best to remove the locking mechanism/door handle since security isn't a issue since it is a home computer. I figure if that was gone a better fan setup could be installed on the grill area there. I am open to any other mods pictures/guides would be appreciated if its something unique.
