I'm in brisbane and have been looking for suppliers of mineral oil, I plan on sinking a few graphics cards in it with a high flow pump and intercooler rad.; Only problem is it seems nearly impossible to get in any quantity, I can source it online but the shipping costs are huge because it's heavy *I need a minimum of 20L. I even tried talking to woolworths about getting me a bulk order of unscented baby oil, but they won't sell in bulk and won't give any discount so it would be about $3 per bottle (500ml) so again very expensive. Does anyone know of any places where mineral oil could be sourced for a reasonable price ? (might really need closer to 60L so cheaper the better).
