A rather interesting cooling solution dubbed "Water Cowboy" will go on sale in Japan in mid-July. It comprises of a 450W Powersupply retrofitted with a waterpump and radiator inside the unit itself.

With an accompanying "external" waterblock for the CPU, the finished systems looks very clean and at 28000 Yen (about $230) it's also pretty affordable, compared to building your own watercooling system, that is!

I think a watercooled PSU is a great idea, if done correctly (that is to say, that precautions are taken against a short-circuit from hell).

I'm not sure that I want my CPU in the same loop, though. Plus, the the tubing they're using to the CPU waterblock in this unit is pretty narrow, probably not for OC'd applications.

Yeh, I can see a line breakage inside that thing not ending too well. You better make sure that you use non-conductive coolant.

I could see using it for ultra-quiet computing projects. It's a great idea.

I dunno... just seems to be one of those Darwinesk situations to me. Why put water anywhere near a PSU that could cook you like an egg in a volcano? Or at least all your equipment...

It's about as dangerous as watercooling any other amp-heavy component like your GPU or CPU. Besides, since this system isn't ment to be unassemble-able, I have a feeling the barbs are very permenant and rugged compared to standard WC equipment.

well, I would think they would hard line it. with copper pipe. would be much better than plastic tube, would make me feel safer.

copper pipe has its disadvantages. If specs aren't perfect, you won't have completely flat seating of the heatsinks on the FETs - or whatever is being cooled. Also, the cpu sink looks to be Al. Don't really want Al and Cu in a cooling loop.

Why not, you dont want any galvanic reactions going on?
