Oh don't worry, we just need something slightly shorter than the ML08.
Volume isn't a problem, 24l is plenty. If it weren't for the width it would fit a full ATX case e.g. the Xigmatek Prospect (162x370x370mm).
The largest, which should just about fit, would be the ML04 (440x105x340mm). Normal ATX PSU and µATX mobo. GPU length essentially unlimited (350mm).
Next would be the AeroCool CS-101 (300x112x427mm) and QS-102 (300x100x415mm). Not exactly the highest quality you've ever seen, but they're quite cheap and they'd fit. Still µATX and pretty much no restrictions on GPUs (240mm) but SFX PSU.
Then there's mini-ITX cases.
Fractal Design Node 202 (377x88x332mm). Mini-ITX as mentioned, SFX-L, 310mm GPU.
Kolink Rocket (235x125x328mm). Same as the node 202, but with different dimension and a bit smaller in volume.
And lastly the Lian Li PC-Q20B (149x235x205mm). This is by far the smallest case and would limit the GPU to 151mm.

This is by no means an exhaustive list. You've really got plenty of options.

#3054
That actually rules out the TU100 (170x277x252mm), ML08 (380x87x370mm) and SG13 (222x181x285mm).
I'll look for a case later today.

#3057
And what are you going to use it for?

#3058
Ok, ignoring used GPUs, which would obviously be cheaper, that means you can get something between a 1050 Ti (150-180€, about the same speed) and a 1060 6GB (250-300€, ~+70%) or 580 (~250€, depends mostly on 4 vs 8GB).
Obviously there're the 1060 3GB and 570 between those, since you don't need the full +70% you could still get a significant upgrade for less money. Obviously it's not worth it if you don't want/need an upgrade, but otherwise those would be the sweetspot.

Do you plan on using FreeSync or G-Sync in the future?

#3052
Keep in mind that the NH-D15 is a bit overkill for this. Have you considered delidding the 8350K?

Did you pick the mobo by features? If not you could compare a few.
Airflow shouldn't be a problem but at the same price there are a few mobos with better VRM cooling or straight up better VRMs. https://www.overclock.net/forum/attachment.php?attachmentid=99753

#3053
Do you want an upgrade (how much?) or just roughly the same performance again?

1. Yes, just for TF2 I'd choose the i3 but for streaming the i5 might be worth it (depends on the settings/quality you're going for).
Keep in mind that most of the benefit for TF2 comes from the higher clockrate so you really have to overclock it. For <10% at stock clocks the upgrade wouldn't be worth it.

2. S = asymmetric, 1 fan instead of 2, all for better RAM/PCIe slot compatibility. If you get RAM without overly tall heatspreaders and a mobo with an x1 slot in the first position that you can live without or nothing (like the one you picked) then the NH-D15 will fit.
Similar options exist, most of them louder https://www.tweaktown.com/reviews/7301/noctua-nh-d15s-style-cpu-cooler-review/index6.html
below 150W Le Grand Macho RT does extremely well https://www.tweaktown.com/reviews/7986/thermalright-le-grand-macho-rt-cpu-cooler-review/index6.html
above 150W I'd put my money on the NH-D15.

3. Yes, 550W is plenty.

A bit higher frequency/lower latency RAM wouldn't hurt for TF2.

Well you can measure your backpack/suitcase to find the upper limit. There's thinner and more cube like cases, I don't know which you prefer.

No? This is Intel, only the most expensive CPUs/chipset are unlocked.
I mean you could get the 2600 instead, but it's not much cheaper or any faster in games, even overclocked, so why bother? But B360+8600 would be cheaper than Z370+8700K and wouldn't make any difference for anything other than TF2.

Ok, no handle does make things easier.
The cases are almost the same size, the question is how small do you want it? There's still a lot of options between that and the Core V1 at twice and the Bitfenix Prodigy at three times the size.
Well if you don't plan on overclocking you can get cheaper components and not worry about the cooling.

I've got no issue with you recommending an aio for the SG13 or you liking the SG13 because you've used it yourself, just don't try to make it out to be something that it isn't.

You can't just assume that everyone wants the same thing you want. You might like that case and if you want that case and want to overclock as well an aio is your only option, but neither of those are a given here.

If you aren't dead set on that case then you can't justify the aio.
If you want a carrying handle the case is right out.
If you don't want to overclock all the worrying about cooling is pointless.
If you want a SFF silent build I'd still go with an air cooler, but a different case.
If you don't want a silent build there's always the fun option of single tower cooler + >=3k rpm fan.

You've recommended a very specific build for a very specific set of requirements (yours) which are simply not given here.

On that note I'm still trying to find out what Domo actually wants. That's why I haven't posted anything more constructive or even a part list yet. He needs to make up his mind about the handle, size and overclocking first.

I don't think you understand. I didn't say it wouldn't offer better cooling. Just that the C7 would be quieter, while also throttling if any significant overclock was applied.

You know that argument is nonsense. A pump + a fan can never be quieter than the same fan alone. Nearly as good at twice the price isn't a compelling argument.
This is about the form factor. Aios only make sense when the form factor doesn't allow for an equivalent air cooler. The problem is if you can just pick any case of about the same size that limitation doesn't exist. You don't have to do insane things like cramming an NH-D14 in a 13l case but you're not limited to aios.

https://www.overclock.net/photopost/data/1452789/b/b3/b3502a11_DSC_0037.jpeg

I mean you saw that the ML08 would fit neither a large air cooler nor an aio so you went with one that only fit aios, but not large air coolers. That's not an argument for aios, that's an argument against that case. So no, your build doesn't prove that you're right.

VRMs and airflow don't matter if the cooler can only handle about 10% more power consumption than at stock.

That's objectively wrong.
Now of course if we're talking about a proper overclock the C7 would throttle, but it would be quieter.

And as always, fuck aios. http://www.teamfortress.tv/post/469342/pc-build-thread
If we're just going to ignore the handle there's enough cases of that size that support full size coolers.
https://www.tweaktown.com/reviews/5982/corsair-hydro-series-h75-liquid-aio-cpu-cooler-review/index7.html
Abou the same temperature as the NH-U12S at the cost of 10dB. And the U12S isn't even that big. You can guess what happens when you use similar fans on both.

#3036
Yes, that makes more sense.
There are few things you could do to save money.
A slightly lower wattage PSU would suffice.
If you're not planning on streaming there'd be basically no difference between the 8600K and 8700K. In fact the lower power consumption might allow for a higher overclock.
You might want to think about whether or not to invest money into overclocking at all. Because there's only so much a cooler of that size can do:
https://www.hardwareslave.com/reviews/cooling/cryorig-c7-low-profile-cpu-cooler-review/6/
The C7 is pretty much at the limit with the 8700K at stock clocks and it's not like there are some vastly better coolers at that size.

#3037
Yes. Although I really doubt that it's off.

#3033
You'll probably regret it in a month.
Any particular shop? I'd use pcpartpicker Mongolia as joke but that's almost as far down the priority list as Finland.

#3034
I'm just going to quote you:

And now you're going to get a case with no handle that's twice as large and can handle full size coolers, but you pick one of the smallest coolers?
Where are you going with that?

#3030
If you didn't mess with the settings it is already on.
Still it would be a waste to pay for a K CPU, Z mobo and a cooler and then not use them. Read a bit more about overclocking, there are enough guides out there. FYI the 8600K's architecture is called "Coffee Lake" so that'll help you find an appropriate guide.

#3031
If you want a white/silver case in that size with a carrying handle then yes the TU100A is pretty much your only option.
The TU200 would be a bit larger if you want an HDD or full size ODD.
If it's just about the size and handle there's the ML08.
https://www.silverstonetek.com/product.php?pid=607&area=en
A bit different, supports a longer GPU or an HDD. If you don't need either then it's just preference.

404, not found, so I'll wait until you've fixed the link to see the example build before I do anything.

#3027
Do you want something similar as in the same size or do you want that case?
Because pretty much nothing will fit in that case. Not the mobo, not the cooler, not the PSU.
Cooler + Z mobo + locked CPU doesn't make sense.
And as always, new CPUs in a month.

#3028
I dislike aios more.

This is trainwreck. Read it again.
Also the Bitfenix Prodigy is one of the largest microATX cases. Really, one of the largest microATX cases. The mini-ITX version is basically a bad joke. It's literally more tha 3 times as large as the one Domo wants. That's not an exaggeration.

The WD Blue is a budget SSD. The are far enough apart that most reviewers won't compare them.
https://www.tomshardware.com/reviews/western-digital-blue-ssd-review,4767-2.html
https://www.tomshardware.com/reviews/samsung-860-evo-ssd-review,5446-2.html

Well if you think all mini-ITX cases are similar then yes. If the goal is "small and easily portable" then no.

PCP wouldn't let you select the components if they didn't fit. Then again this case is rather large.

#3024
That's technically impossible.
The all core boost is 4.1 GHz so 4.0 GHz would be underclocking.

Also it's either "degrees centigrade" (before 1948) or "degrees Celsius" (since 1948) or just "degrees" (since the 19th century outside of the US and UK) but never just "centigrade".
Or you could just write °C or even just C if you can't find °.

Positive: less dust.
Slightly negative: slightly better cooling
Negative: Worse cooling but you'll never have to vacuum the room ever again.

Also fan ratio doesn't say all that much. The fans might be different and the GPU also pushes some or all of the air it sucks in out of the back (depends on the cooler type). Dust filters also reduce the flow a bit.
So 1 intake 2 exhaust can very well mean a >3:1 ratio for exhaust.
Negative air pressure without dust filters on the intakes basically guarantees that all the dust in the room will accumulate in the case.
Same number of fans for intake and exhaust + GPU and/or dust filters on the intake already cause slight negative pressure.
I'd say minimum 1 intake, 1 exhaust and always at least as many intake fans as exhaust fans (preferably exhaust+1 with dust filters). Without dust filters 1 intake fan can be enough because you'll have to clean it regularly anyway.
Of course Sometimes the CPU cooler is so close to the rear exhaust that you might as well count it as exhaust fan (especially with dual or triple fans setups) and you can reuse the actual rear exhaust fan for a different position.
So the absolute budget setup would be 1 intake and abusing the CPU cooler as exhaust fan.

In your case with 3 fans 2 in 1 out is really the only viable option, especially if you've got dust filters.
