Hi all, I have a quick question for everyone. I've run into a snag on a build I'm working on, and wanted to ask for some advice. Little background. I'm building a new server and decided to passive watercool it using an Aquacomputer 1800 rad that's been sitting in a garage for ages. In the old setup I had it in I used it nasty plywood chassis I threw together, see below. Yer it looked ugly, but it was completely silent, the HDs were noisier than the PSU fan . I've whipped up a stand alone frame for it since it's too large for anything else. I had considered using a second coolermaster cosmos so that the server and rad unit were the same, purely for looks, but couldn't justify the extra cost. So the frame has some quick disconnect attached to the rear hoses, but the flow constriction is appaling. To make matters worse, the aquacomputer res there is 1/4" threaded so yet more flow constriction there. I've switched the laing d5 pump I was using for an old eheim 1250 and that has improved things, but not enough. I'm still bleeding it at the moment, but I'm not holding out hope. My next step is to switch the pump for a 1260, with more flow and a better head height, and the res for an EK tube res with 1/2" threads. But the last remaining thing I want to switch is the quick disconnects. What I'm having trouble with is finding some genuine 1/2" ID quick disconnect fittings. The best I've found are these, male coupling and female coupling. I'm still not convinced, but these are 12.7mm which is as close to a 13mm(1/2") fittings as I can find. Obviously this is a bit of a strange setup, and one with a lot more head height requirement than most setups. I just wanted to get everyones opinion really before I move on. To make matters worse my main rig died on me a couple of days ago, so I'm now really on the clock to finish this so I can get round to rebuilding that to. It never rains but it pours. Last pics, the server itself. Made one addition since I took this pic, added an Areca 1220 raid controller for the 8 2tb drives to run in RAID6, was going to go with raid 5 using the GA-X58-UD5 but I just can't bring myself to risk an array loss under RAID 5 with this many drives.
