A little update, for people who actually read this log. Got 45 degree rotary fittings in today, so I was all excited to finally fit my radiator. Well, it fits, sorta, but the fitting is applying a lot of pressure on the PS/2 ports. Now I don't give a rats ass about the PS/2 ports anymore, but I am wondering if this is going to cause trouble. It's definitely not ideal. Also, there is no way I can make the 4-pin power connector fit at the top, unless I cut off the "clicking" mechanism. There certainly is space to fit the cable, but not with the secure-lock click (whatever it's called). I could of course not use a fan in that location, but that defeats the purpose of having a 420 radiator.... In hindsight, I wish I chose a 360 rad, oh well.
Probably not too clear here, but the fitting is putting quite some pressure on the PS/2 ports... You can also see a temporary DangerDen reservoir I picked up at the local Microcenter.
Bought a dremel today, so I am going to cut the top part of the bay out later, so that the 3rd fan from the back will have some useful airflow. Also, I ordered two GTX 480s (only $420, how could I resist) and got two DangerDen full cover waterblocks! These will arrive somewhere next week. Now I don't think my 420 rad will be able to keep all of those cool, so I am looking at a 240/280 rad for in the bottom. Probably going to be a 240, because I have 120mm fans lying around.
I would also like to make a fill/drain port. On the back of the top radiator there is a port that I could possible use as a fill/drain port. If I would want to drain the system, all I would have to do is turn the case 90 degree and open the port, and let gravity do the rest. Hopefully this picture clarifies.
I would drill a hole and put some sort of G1/4" plug in there for easy filling/draining.
