bigben2k: Either way... I'd consider ducting (a large duct) from the front, using 1 or 2 bays, since there's plenty of space.

Well I still don't see why I need to sacrifice bays, when there is a HUGE space on the front of the mobo side that seems like it's begging for a rad. The mobo chamber on the YY cube is fairly narrow, just wide enough for the mobo and some full height cards. The AMS CK1100 case is MUCH wider (16.5"), mostly on the mobo side. The CK1100 is also longer (21") than the YY case, with almost a full length 5.25" bay in front of the mobo tray.
Thus, under the 2 5.25" bays on the mobo side is a space about 11.5" high, almost 9" wide, and about 5" deep with nothing in it but 3 80mm intake fans and the PC speaker. If I make a big enough hole, I can slide the rad out the front of the metal case body about 1.5" (30-40mm) and still leave it inside the plastic front bezel.
The downside is that this space is the only place on the front of the case forced air intakes can be put unless one uses drive bays to mount fans, which is possible but awkward. The back of the case has mounts for two 120mm fans (one in each chamber) plus the PSU and it's fan.
I am going to use a BIG rad. Until I found that the heatercore database listings don't include the tanks, I was thinking of the 2-206 or equivalent (10.75"x 6.125" x 2") However If I have to include tanks, then that one would be a bit to tall, and I will have to find something shorter but wider. I have seen something about the tanks adding about 2" to the listed height, which means I need something about 9-9.5" tall, and around 8" wide.
If I ducted the rad out the side of the case, I would need to either add additional blowhole intakes in the side of the case (which would stick into the mobo space, and mean additional fans / noise) or let the case run at negative pressure sucking in through the stock vents on the sides (which I was planning to cover with sound insulating material).
IF the rad will only warm the intake air a degree or two over ambient(and nobody has said differently) then I don't think it is a big issue to use that same air to pressurize the case, and save on fans at the same time.... I'd put the fans in a rotor style plenum so they blew over the mobo. If the mobo side of the case is pressured, air will naturally blow into the PSU side, and out the PSU fan and the two 120mm exhaust fan holes. If this is sufficient I could probably even leave the exhaust fans off most of the time, further reducing noise.
I can stick the pump on the bottom of the case on the PSU side, just under the PSU. The resevoir and fill tank I can put on the PSU side between the PSU and the drives, with the fill cap sticking out the top of the case, or possibly recessed into it. The net result would be that the only plumbing over vulnerable parts is what goes to them, which is kind of hard to avoid.
Another reason I don't like side intakes and exhausts is that this case will be going on the floor, probably under a desk. I'll want to push it to one side where the side of the desk will tend to obstruct airflow. If I push it to the other side, it will be blowing air on my legs. OTOH, the front will stay clear just because it's the front, and the back is going to have several inches of clearance in order to have room for the cabling.
So far what I've been seeing is what you are going to do, but no reasons NOT to do what I've been proposing....
