As for choosing quiet components, there is some truth to that, the component does have to dump it's heat into the air inside the case, but that's only part of the problem, the other part of the problem is keeping the air inside the case cool enough that it will readily absorb heat from the components, which is the side of the problem I'm working on now. I'm working under the assumption my system wide tdp will be 500w max and intake air will be under 30°C. I don't want any of my components over 70° C, the transition from die into heatsink is about 20°(base of heatsink is 20°cooler than core temperature) under load on my nehalem chip, may be higher w/ ivy, so for now I'll call that 25. How well the cooler dissipates to the air inside the case is more variable, and I don't have good data on heatsink base vs ambient, so I will split the remaining 25° gradient halfway between getting it out of the heatsink and getting it out of the case. Given the specific heat of air (im using 0.03 kJ/ K ft^3) the power (.5kJ/s) and the temperature difference (12.5K) we can calculate the absolute minimum usable CFM at 45, assuming perfect distribution of heat into the air (all exhausts equal temp, and all the air going into the case absorbs heat before it exits the case.) That's a lot lower than I thought it would be, I think either fan manufacturers are lying about their flow rates, I've made a mistake in my calculations, or I've got way more air throughput than I actually need.
In any case, at least I know I can turn the fans down low and still have enough flow to cool adequately. If there are any problems in cooling they can probably be solved with ducting.
Can you describe suitable?
I'm guessing small, but what else?
Compatibility with high performance parts is a must, I'll be livestreaming sc2 at at least 720p, 1080p if I can find a new ISP(I know most viewers couldn't tell the difference without the option to select it, but they still complain), which would mean I can fully saturate an overclocked 4 core i7 in regular use(probably 3770k). GPU will be a 680 with aftermarket cooling, seems to be the best performance per watt. I have no need or desire for SLI or crossfire, that said there is currently room for it, and unless you can think of something better to do with the space I'll leave the option open for a big GPU cooler.
Quiet is also a must, but not necessarily while im fully stressing it, hence the fan controllers on front. This machine will be on 24/7 in my bedroom, so it needs to be quiet whenever I'm not using it, or only playing music/video.
Filters on ALL inlets.
It must also be vibration resistant and small, I'll be taking it to LANs. (hence the h100 instead of a large tower cooler, don't want one of those attached to my mobo when I'm bouncing along the road, it would take some pretty convincing drop tests for me to change my mind on that.)
Lastly, it must not look like Optimus Prime took a dump on my desk, while a minor consideration compared to the rest, I do not appreciate windowed cases, parts of the case that jut in or out for no reason(e.g. NZXT Vulcan) or pointless LEDs(I'll still buy them if the product is otherwise the best option, but there's a good chance I'll desolder them.)
Does the case have room for a tall CPU cooler?
5mm for mainboard standoffs, 3mm mainboard, 7mm cpu and socket, 165mm cooler -> 180 mm. plus mainboard tray, room behind the mainboard tray for cable management plus side panels. My case would be about 200mm wide minimum. Then I would think about adding a little to fit an 140mm exhaust fan...
Room, maybe, it would be simple to MAKE room for one if there isn't, but I don't currently have any motivation. Right now the whole case is 20 cm wide, 3.16cm of that is taken up by material thickness and cable management space. I'm using fan controllers designed for 3.5 inch bays so I'd have to make case wider rather than the cable management area smaller. I'd have to add 2.5 cm to the width to add a 140mm fan on back instead of 2 92mm fans. As those fans are probably going to be super low/off most of the time I think that can wait till revision 2.
