I do IT support for a couple of machine shops. We just replaced PCs at several machines and the ones we swapped out are a sticky mess from coolant mist and dust. I'm hoping to retask them to office and assembly areas. Keyboards and mice are cheap to replace. But this gunk gets into the power supply, CPU heatsink, and video card fans and causes them to fail or slow down. I'd love to find a way to protect the new PCs from this. I know enclosures exist with filters for dust, but do any protect from the fine coolant mist that permeates the air?
