HP do a off the shelf water cooled EVRYTHING rack mounted server designed to run off the chilled water system that normally cools the CRAC units (down flow air cooling). These hp servers cool the cpus, memory hard drives controller cards, chip sets and psu's (though in larger gateways the power is centrally supplied) And it has all solid copper tubing and headers.

I had this board, never used it though as I could never find the matched CPU's so it landed up in storage then went missing. Shame that. Brings back memory of the days I was earning too much, but because of the learning experience I rarely have single processor gaming rigs. Intel wasn't the only motherboard company that was trying out this type of thing for sli/crossfire
