So I'm on the verge of finally having everything I need for a 12600k build and I was planning on using my old mid tower case (with new fans) for the new parts. I'd like to have everything all beloved patriot and span and plan on cleaning the case after removing the old components. I was wondering if there were any products/tools I should avoid. Should I only be going to town with canned air? Microfiber clothes are great at grabbing dust, but will they create unwanted charges in the case? Any recommended products/methods for prepping an older case?
