The backround: I'm looking for a case that is easy to transport, but sometimes I need to do very intensive computations fast.
I pre-ordered sentry, as it's the most mobile case that I was able to find, now I'm thinking if there's a way to mod it to get better cooling while not sacrificing much of portability.
Has anyone considered placing a bunch of presure optimized NF-F12 outside of the case blowing into the case? They can be easy to attach, remove.
Sure you can do that. Magnets would be simple, clean, and easy to remove. You can attach small strips around the fans with glue/epoxy and it should hold fine. Now I would like to ask, what specs do you plan on putting in the Sentry that would possibly warrant the need for fans on the side? If you have a LGA 115x socket I suggest picking up a LP53. It's a fantastic cooler for its socket size and form factor that Ej24 has tested as well as some folks over in the Dan case thread including dondan.
