The majority of pro FPS gamers prefer 24" 1080p displays to keep the most amount of the game in peripheral vision as possible, without sacrificing detail. 144Hz is a given, and gsync/freesync isn't absolutely necessary, but is a great feature to have. If you haven't used an IPS panel for an extended period of time before, chances are you won't be disappointed with a TN panel anyway. After all, you get use to whatever you're using pretty quickly. Unless you have a need for an IPS panel or the colour representation is important to you, it's just an added cost. Some people will notice the increased gtg input lag, but it's not substantial.

I'm unsure of what kind of budget you're trying to work with, but in that case I would be sticking to an all-black motherboard such as the MSI Z370 Gaming M5 Motherboard (although it is pricey). And then for the case I would probably go all black, and keep the white for the components, since you don't really get many black-with-white-accent cases. But that would depend entirely on your budget. Something like an NZXT H700i in either black (or if you were happy with that much white, the black/white one).

I don't know of any that can be purchased, however if you had access to a laser cutter/had a laser cutting service located nearby, you may be able to talk to them regarding getting a design cut out of the front panel.

In that case you'll certainly enjoy using a 1440p 144hz monitor. I personally would take 144Hz over 4K any day. That being said, you get use to whatever you own. When I first purchased a 144Hz panel I couldn't even look at a 60Hz panel without makes my eyes feel strange. Then I went back to 60Hz Ultrawide 3440x1440 after a few years for various reasons and it doesn't bother me much at all, because I don't play competitively anymore. But I would also consider looking at getting a decent ultrawide 1440p display with a decent refresh rate. Costly, but very much worth it.

I would also say 1440p 144Hz. You're certainly not wasting your money going that route. It feels quite different to 1080p 144Hz. That being said, if you're super competitive in FPS games like CS:GO, the larger monitor can be somewhat disadvantageous since there is less of the game in your peripheral vision. But otherwise, I would recommend 1440p 144Hz.

No worries. Best of luck!

Although pretty much everything I personally do is for aesthetics, at that price range i'd be looking for a nice, clean case without a side-panel window and be settling with the best components I could get my hands on. As @Jurrunio said above, on a low budget (or any for that matter), buying used is a fantastic way to increase price to performance.

I get all my technical drawings off Protocase's website when designing custom cases. They have an extensive list of resources for not only ATX specifications, but also enclosure design tips if that's something you're interested in. There are also various 3D CAD models available on GrabCAD which model the exact dimensions required for screwholes/standoffs/io etc.

Congrats on finishing up the PSU Shroud/Pump and Res housing. It's those small details like these that go unseen that make a build special. So clean. Can't wait to see this one finished

I believe the 'shitty' airflow thing has been exaggerated a little. As @foamygopher said, a CNC-milled front and/or top panel will improve temps dramatically, but don't expect to be frying your components with the stock panels. My build in the Enthoo Evolv (albeit with a custom loop) on a single 60mm thick XE360 triple radiator for a 6600K and 1070 never reaches high temperatures, with my fans at max 900-1000RPM at load and hardly even turned on at idle. On air, as long as you're not running AF-optimised fans on a thick radiator at low RPM, you shouldn't have any issues. Just pick the right fans, and set up fan curves accordingly and you'll be fine. There's a reason it's such a popular case.

Monitor(s): TL;DR - I'd choose a single 4K panel over triple displays unless you frequently use racing simulators. It's all very subjective, so nobody can really tell you what's right for you. As someone who uses their system extensively for productivity, a 21:9 monitor or multiple 16:9 monitors is essential. I do a lot of CAD work, so I do prefer higher resolutions. If you play a lot of racing sims, perhaps triple monitors would work well for you, but unless that's really important to you, I probably wouldn't recommend it because you'd be paying a lot of money for high-refresh rate monitors that may just sitting with a static image or webpage on it most of the time. I used to own a dual 24" monitor setup, with an Asus VG248QE 144Hz and an Asus VE248H 60Hz, both of which look virtually identical, but with different panels. What was great about that was that I could do single-monitor gaming on the 144Hz panel, but had that second panel for productivity, without paying the premium for another 144Hz panel. I now own a single Samsung S34E790C 34" 3840x1440 Ultrawide which is great for video editing, and still very good for CAD. Better panels can be bought for gaming though. I'd perhaps consider this, or maybe dual 27" 1440p monitors? Liquid Cooling: Custom loops are expensive. Virtually all my builds use liquid cooling, but that's only because my builds are almost entirely based on aesthetics. With the 570X, there's plenty of glass to show off a nice loop, but it truly comes down to whether you're willing to put in a bit of time, and have an appreciation for the aesthetics that come with it. Otherwise, it's a waste of money. Leakage should not be a concern, nor should be the task of doing it. Maintenance is always going to be a thing, but honestly it's not bad at all. If you're using a maintenance-friendly coolant, you shouldn't have any problems at all. A few hours a year worth of maintenance at most. If you wanted to take that route, feel free to ask me any questions. I build water-cooled systems for fellow Aussies regularly. I'm more than happy to help out, or I could talk you through the process. Might save you some cost.

I would consider upgrading to a 1070. If you had the budget you could go for a 1070ti or a 1080, but at that resolution it's not all that necessary.

I would say that an upgrade isn't particularly justified from your current system. Either way you're going to be buying a new motherboard, in which scenario you'd probably be better building a dedicated streaming PC and keeping your current system if you're serious about streaming. But if you were going to upgrade, I would say 7820X.

It's just such a subjective thing. Nobody on here can tell you what will look good to you. I always recommend you build a PC incrementally if aesthetics is at all important. Buy the case and a few core components, then a few more, then a few more. That way you can make decision as you go rather than all at once. It will cost a little more in shipping, but you have a much better chance of being completely happy with your final system. The same thing applies for cables. I would wait until the end of your build to order them, because you would be ordering them from CableMod separately anyway.

My personal opinion is that black/carbon/white/blue/red are a few too many colours for a build. That being said, it's entirely possible to make it work. If I got this brief from a client, I would probably recommend keeping to fairly simple cables. With all those colours, it will end up being very 'busy' inside the case, which again, in my opinion is unfavourable. I couldn't say exactly what I would do, because it's difficult to visualise. Just keep in mind that matching colours is difficult, and if not done correctly can really throw off a build. Since cables are the last thing I do in a build, one technique I use sometimes to visualise cables before I purchase materials is to develop a 2d pattern in photoshop of the colours as 12 long strips for instance for a 24pin ATX, print it out onto paper, cut it to length and then place it in the system. Just a little trick if you want to get a bit of an idea before buying the cables. In terms of lighting, I would definitely be sticking to natural white. So RGBW diodes would probably be necessary.
