Okay, I've been lazy, and my roommate's digital is out of batteries, so no pictures for this update, but I am nearly there. The plexi shroud was a pain in the *** (never, ever, ever, ever dremel acrylic. Use a bandsaw, I have melted plastic still imbedded in my arm.), but its done, and on the HC, and the Fan-Shroud-HC assembly is fixed up there in the roof of the PC-60 with 4-40 threaded rods.
The intake duct, as of now, as been scrapped, because between the bottom of the HC and the start of the Motherboard exists about a centimeter and a half of space. Obviously as the HC travels forward, there are no restrictions, and indeed I have a full two optical bays left. However even with a large duct that recedes by the motherboard (most of the rear 120 would have to intake via the cm and a half space) and expands to a good 2 inches deep up forward, I think the restriction of such a narrow air channel for most of that rear 120 would be disadvantageous. This isnt such a bad situation, as I have 4 panaflo 80's on intake both at the bottom front and at the rear back. Because of this, I anticipate near-ambient case temps and no deltaT problems between the fins and the air.
Im currently leak-testing with 90% distilled 10% blue VW antifreeze(not pentosin, just dealership STD). Going slow and steady, the antifreeze I think initially really frothed itself on the first pass through, and the microbubbles abound.
In a few hours or so ill get the camera up and give you an idea of those spacial limitations for the intake. Its a bummer to give up the only sort of original thing to the mod, but the space just isnt there and the performance is really whats important here rather than the originality. More to come.
