The Samsung has good reviews, but it is not as good as it's price. The LG 32GK850F-B has excellent reviews, but is half the cost. I have it's older brother, the 32GK650F-B, which has nearly as good of reviews and in fact I have three of them, two for my main rig and one I'm using elsewhere, and even mine with the 5ms response time (1ms using blur reduction) is the best monitor I've ever personally owned. The 850F-B with it's native 1ms response time has to be that much better. I don't think you're actually getting anything worth an extra six hundred dollars with that Samsung display. I sure as hell wouldn't spend my money on it.
The 240hz is mostly wasted because you're not going to hit anything near those kind of frame rates at 1440p on any major AAA titles, at least, not without dropping settings greatly. And the G-sync, while nice, doesn't justify twice the price over models with Freesync that are verified G-sync compatible and work just fine.
Again, it's your call, but heck, you could get TWO 1440p displays, REALLY GOOD ones, for the price of that monitor.
A 240mm cooler isn't really sufficient for the 9900k or any of the 8/16 CPUs. It will work, but it will likely struggle. Especially if you live somewhere with a high ambient temperature, which you almost certainly do. We have moderators from Canberra and NSW and they tell us how hot it is during the warm season.
At this kind of price, you want an NVME PCIe M.2 SSD which is much faster and has a smaller footprint than a SATA SSD.
The case I selected is a great case, but my first choice would probably be the Fractal Design Meshify S2, however it is another 100 dollars over the price of this case. Both are very good choices, as are a good many others. Forget about the Cooler master Silencio. It's not a good choice. It has too thin construction for a high end case and it has problems with radiators for a lot of cooler models that are a little bit thicker. It also has punch out PCI covers instead of screw in ones, which sucks. Very little room on the backside of the motherboard tray for cable management. Very few pass-through grommets for cable management.
Yes, it's a cheap case, but it acts like one, and therefore has no business in a build like this. You'll regret it if you go with a cheap case. Not because of any fancy lights or anything like that, but because cases that are more expensive tend to be more expensive for a good reason. They have features, or include fans, or are solidly built, to justify them being that price most of the time. Most of the time.
You don't need an 850w power supply for this build, either yours, or mine. Not unless you plan to wait and go with the Nvidia 3000 series RTX 3090, which requires a good 850w PSU and likely will need one with a special auxiliary 12 pin power adapter.
I'd do something like this, which is less expensive but if we're being honest, is a much better configuration than what you had chosen in many areas.
Also, if you're going to buy an Nvidia based graphics card, you buy EVGA. No question. Every time. And if you want, you can add 2 or 7 additional years on the warranty on their graphics cards for a very reasonable price. Like 30 bucks for an extra two years over the three it comes with, and 60 bucks for an extra 7 years. US prices of course but I'm sure they have something similar for your region. Regardless, they make the best Nvidia based gaming cards, hands down.
