Here is my third ION Case mod. This one is liquid cooled with mineral oil (does not conduct electricity like water does), the oil flows through a waterfall and goes over the ION board and then underneath it where the hard drive is. The oil is then pumped back up to the top of the waterfall. Not only does the waterfall add looks but it should also help cool the oil. The best solution for the blu-ray drive is to have it external to keep the case small, but you could easily expand the base and place it next to the hard drive having it open on the right side of the case. The hard drive and blu-ray drive would need to be sealed from the oil (because of the spinning parts). Heat sinks could be placed on them to help draw out the heat into the oil. The power supply would be the picoPSU to save more space. The pump power could be tied into the psu (recommended) or could have its own plug. Also plexiglass could be put over the top to protect it and keep out the dust. Lights can be added for a more dramatic effect.
