Wow thats one heck of a system. Now as for cooling . Lets see. The Lanboy comes with space for 2 optional fans one in the rear and one in the front. Then of course the fan and heatsink that comes with the proccy. To be frank I think you should be ok with the heatsink and fan with the above config. But why waste two optional fan slots. Id say place those fans along with the proccy fan and heatsink and of course use Artic Silver. now remeber IM assuming that you are buying the Lanboy and not the SUper Lanboy which comes with 2, 120 m fans I think.
As for the P180 , now thats a totally different story. That thing is built for some heavy duty cooling. Here check out the the Cooling specs for the P180
Cooling System:
1 rear 120mm Tricool fan (standard) with 3-speed control to balance quiet with cooling
1 top (standard) 120mm TriCool Fan
1 lower chamber (standard) 120mm x 38mm (thick) TriCool Fan
Antec Quiet Computing Air Duct for better, quiet cooling of the graphics card
1 front (optional) 120mm fan
1 80mm fan (optional) for graphics cards
Either way i think both cases would be cool even if you threw it in fire

Are you referring to these cables
http://www.antec.com/us/productDetails.php?ProdID=77226 Antec calls them Cobra Cables Im pretty sure you dont get Antec Cobra Cables with any mobo. However you might get others which are wrapped around the same way. I believe theres a thread on this forum on how to make the same by raven I think.
