First and foremost...this IS happening so naysayers just go away :). Now that I've got my new computer on the way I'm going to start my custom project for my laptop. G73-JH. I plan to build a custom enclosure for it but I have a few questions and would love any input before hand.

Here's the cart so far (fitting sizes may change ) : http://i.imgur.com/KabOP5m.png

questions : (looking for input)
1. Fully sealed enclosure? I plan to make it a fully sealed loop. No air in or out, possibly will need a bleed valve or box but those are abundant.

2. Heatsinks / fans (pic of mobo w/ heatsinks and fans http://i1.ytimg.com/vi/bWF2c85CmpU/maxresdefault.jpg) I'm contemplating keeping the heatsinks on and taking the fans completely off, and most likely the copper tubing as well. What do you guys think?

3. pump issues? The pump I have in my cart is a nice but small-ish pump at 11 psi and 158gph. My worry is in my case it will roughly be 24x12x6-12 will I cause a flow through ? where there is pressure being pushed into the intake and causing the pump to freespin ? I know this can be an issue with air, idk about oil though.

I think that's all for now. Thanks in advance for any advice. It'll probably be a month or so before I start actually building this, but there will be plenty of pictures :).

Hi
Although i am unfamiliar with the specifics of what you are attempting I am aware that it has been tried and know the theory also as a mechanical/electrical engineer i have some experience with cooling of large plant and mineral oil filled electrical transformers,so just some thoughts.
If you are going to use a sealed box with the intention I presume to prevent the ingress of dust then a bleed valve will not work as when the oil heats up and expands it will vent oil/air out of the bleed then when it cools down the bleed will not allow air back in which will cause low pressure in the case and probably lead to failure of the case.Better is to have an open vent on the top with an air filter attached to it.
I don't know what you...
