Grommets come in a range of styles (cable exit, cable sealing, sleeved, blanking) but the ones u want are like a rubber doughnut with a groove round the rim. Just grommets.<P>For fans I use a 4mm ...

If you’re not sure what I’m on about a water cooling grommet is a rubber-lined, circular cut-out in the back of a case that appears to be designed to have water cooling tubing passed through it.
