I don't have much time, so I'll run through this quick. I went with 2 danger den maze2-2's in series, with a 5 ft., 8" PVC bong with a 5 gal. res. The tubes run into the case through a faceplate with holes in it. I think I would have liked to drill holes in the side for the tubes, it would be easier to work with in the case, but the side plate slides all the way off, so it would have been awkward. Or maybe lower in the front. I should give it more thought either way. Then I cut out a hole in the top(exhaust) and front(intake) for 120mm fans. I really wish I had a camera. Oh well. The pump is a danner pond master 1.9, $35. I don't remember for sure, but I think it puts out about 60-80 gph@5 ft. I would go bigger and maybe with a different brand. The pump went out last week, but I have the replacement impeller already, so I am less ****ed off now. I was freakin' out when I woke up to silence, FREAKIN' OUT! Make sure your board shuts down if things get too hot, either from bios or temp mon. software. FREAKIN' OUT! I also cut the back out of the case above the PS to mount 2 80mm exhausts. I have a lot of exhaust cause I haven't had time to put the final hole in the case for a 120mm that will blow in on the board over the northbridge. When that's in, it should balance airflow, with a little more exhaust than intake. With the adjustable fans though, I just cut back on the exhausts and crank the intake. I added a 40mm fan on the northbridge HS, but I would like to take off the HS and come up with my own cooling solution(and make sure there is grease and good contact down there). Also, there is now a hole on the MB tray behind either CPU with a little 50mm fan blowing on the bottom of the board. I figured it couldn't hurt to get a little air flow on the bottom too. There's an 8 rheostat fan control array on the front of the case now too. You can never have enough fan control. I would start simple, but keep the future in mind. Had I thought that maybe that 1 ft. would actually turn into a 5 ft. bong, I would have spent the $15-25 more for a better pump, or at least looked harder for a better pump in the same price range. The main thing I wish I would have done for everything is post my idea's before I did it, just to get some feedback. I started coming here after I was done with two machines. Doing it all in a vacuum like I did, I had to do it to find out whether it was a stupid idea or not. Which is good cause I learned a lot, but bad cause I wasted a lot of time and money. Wow, that wasn't short at all. Hope it gives you some background or some ideas. And yeah, the MSI sucks for tweakability, so the Asus looks like the top contender for now. I would like to see some article's on what's to come in the near future for boards and to see what is in the future with the t-bred and hammer series coming out. I am going dually hammer next(unless the horizon is brighter when the day comes), I wonder how long a wait it will be. I waited 2 years for the dually athlon.
