never get gaming membrane boards.
Membranes can be pretty good, but gaming stuff is overpriced.
Best membrane you can get is probably some office-oriented stuff.
try out a g305, you can put a lithium AAA instead of an alkaline AA with a simple mod that's literally just stuffing foil so the battery makes contact and boom you got 81g.
Sorry for not responding sooner. I have a noctua nf-s12b redux for my unfiltered exhaust, stock fans for top exhaust and a deepcool 240 ex AIO as an intake. Thank you.
