Just put the HAF Stacker together with my build. Man this case is awesome. Sadly, the screws that came with the case and the screws that came with my Seidon 120m aren't long enough. Mounting it up to the 915R. They're just a couple threads short with the air filter on, and the screws that came with Stacker are even shorter by like 1 thread. If I take the filter out of the side panel, mounts up just fine, no problem.
Any thoughts on this? I'd rather have the air filter on. BTW, I moved from the Storm Sniper case, and after I got everything put together, my temps on my cpu dropped roughly 10 degrees. Super awesome case this is.
Edit: I should also mention, I'm doing a push-pull. Screws aren't long enough to go through the side panel, air filter, standard size 120mm fan, and then reach the radiator. Just a hair short.
