You'll have to buy cables for the specific power supply you buy.
The cables are not universal, for example cables for EVGA psu won't necessarily be compatible with Seasonic or Corsair power supplies. 
 
For example, Cablemod lists what ready made cables are compatible with here: https://cablemod.com/compatibility/
they also have a custom order page, where you can specify what power supply you have and then choose cables : https://store.cablemod.com/configurator/
 
The power supply you chose (Silverstone SX750-PT) is made by Enhance which is an OEM that doesn't retail power supplies (like Seasonic or FSP) so there's no guarantee the modular connectors on the power supply are the same as on other power supplies.
 
The company that makes the cables must specify the cables as compatible with your psu, or custom make the cables for your power supply.
 
Alternatively, you can determine the pinout of the connectors on the power supply and compare it with the pinout of other power supplies.
 
 

Does it have to be over ear? I bought the Sony WF-1000XM3 and it's the best bluetooth earphones I've ever bought.
And the ANC is really excellent too. I bought it sealed from marktplaats for €120 excluding shipping.

@NeuraCodeThe noise cancelling is decent but its far from something like a sony wh-1000xm4

Just don’t get anything from vmoda they make the most uncomfortable headphones I’ve ever worn 

@NeuraCodeI have the hd50bt from senneheiser and they are really comfortable. Even after 10 hours of gaming sessions (non stop) they are still comfortable. I've never had a problem with the bluetooth and it has clear sound. Hope this helps!

vCore is a virtualized CPU Core/Thread. It's not dedicated and may not even actually exist on the host. What it means to you as a end user, is that you are being allocated enough virtual space to handle 80 threads at a single given time. In terms of how fast these vCores are, there is really no way to tell and it would vary based on other unknown virtualized instances on the host and how heavy they are hitting the host at any given time.

I'm pretty sure it's just "thread", as Windows' Task manager also calls thread "logical processors":

 
Looking here: https://docs.microsoft.com/en-us/azure/azure-sql/database/service-tiers-vcore?tabs=azure-portal
We can also see mentioning of hyperthreading, next to vCore, furthering that suspicion:
 

Azure is offering 80 virtual cores and calling it vcores.
vCore in your BIOS is voltage for the CPU.

If the floor is not an option, buy a wheeled mount for the desktop chasis to raise it a few inches, or invest in a rack and rackmount chassis. I would highly recommend not putting computers, especially desktop computers in any room with no ventilation. Like a server room, at the minimum has it's own air conditioner to keep the temperature under 30C.
 

Pretty damn unexciting, but rather useful.

Linux and Windows have different benefits (and drawbacks) depending on your use case. For a CS student there are definitely a lot of benefits:
compilation toolchains make infinitely more sense on Linux - seriously, it's night and day the terminal is more customizable and useful (even though powershell has made some big steps forward), particularly when handling text files Linux distributions have used package managers for decades; these are tools that let you install almost any software that is available for your system with a single terminal command (without having to look for installers on the internet) and let you keep everything up to date, again, with a single command a lot of developers use Linux for their personal projects (see above to know why) and therefore a lot of development oriented open source utilities and libraries are written with Linux in mind and are only ported to Windows as an afterthought - if at all you can literally edit the source code for almost anything on a Linux system, which can be extremely helpful for understanding how an operating system works (though of course you could also edit Linux on a Windows system if you wanted to).

As a counterpoint to the benefits of Linux, have my tales of woe.
 
My biggest gripe with Linux is I have never had it work out of the box on a system I would actually want to use. Desktop with a GPU? Screw you here's a random black screen. Uncommon wireless hardware? You don't deserve WiFi. High DPI display? Take a hike nerd have these tiny icons. Laptop with Nvidia Optimus? Do it manually.
 
For all its faults, Windows has worked flawlessly on these all these machines I described WITHOUT spending hours digging through forums and config files, and that's more valuable to me than the benefits Linux brings. And combined with WSL and a VM I have yet to find something I could do on Linux that I can't do on Windows.

You can dual boot.
 
For CS I asume you mean C#, .Net is alot less common in Linux, where Languages like C, C++, Python, Rust are more favored.
For .NET you will be using Mono, which may or may not be different than the implementation on Windows.
For things like C and C++, you will need to learn to use Makefiles. Things like Visual Studio in Windows do something similar for you, but its completely automated, in Linux you will be making them.
Most things are expected to be open-source. If it's not, it will likely get pushed to the side in favor of something that is.
If you plan to target both Windows and Linux, you will need to familiarize yourself with cross-platform SDK's, you can also look at QT
If you plan to do web development or work with Databases, it will be pretty much the same.
If you use applications like 3DS MAX or Photoshop, you will need to learn to use alternatives.
 
You are free to customize Linux to fit your workflow.
Some people like the GNOME Desktop Environment because it stays out of the way.
Some people like me like the KDE Plasma Desktop Environment because its heavily customizable.
Some people like a file manager that has tons of features built in, some like a rather basic file manager like what you get in Windows.
 
So basically, Linux biggest advantage is customization and you are free to do what you want with it.
 
You should only switch to Linux if you like Linux. Download a couple distros, give them a spin and see what you think. If you like it, make the switch, if you don't then don't.

In my opinion and experience, the only reason(s) one should use Windows is if:
 
1. They are required by their job or school to have Windows on their device
2. The majority of the games they play use kernel-level DRM and/or anticheat, rendering the game completely unplayable even with Proton
3. They absolutely rely on the full (not online) Microsoft Office suite, Adobe CC, etc, and cannot live with either cloud versions or alternatives (such as Libreoffice or Openoffice)
 
So you might as well try it out. No harm in doing so, and you can always just run it from a USB.

Virtualization, running my own phpmyadmin and apache, stuff like that.

Hi,
 
8GB should be sufficient for the tasks you mentioned.
 
I've recently bought a Surface Laptop 3. I wanted to get the new XPS 13, after my surface pro 3 died, but then I've found a deal on the base Surface Laptop 3 for 700 Eur. Even though I'm not particularly happy with the mediocre hardware/software-integration on microsoft devices (they all have random issues, which never get patched), it was a compelling value. Especially since you can upgrade the SSD yourself without leaving any marks (warranty!).
 
I was concerned about the 8 GB of RAM as well, especially for development, but it has not been an issue for me so far. You cannot really host any VMs, but then again, the new intel chips might be fast, but they also reach their thermal limit pretty quickly on such thin devices.
 
Value-wise I would strongly recomment the base model with an DIY SSD-Upgrade, if you are ok with the alcantra finish (which is actually kind of nice to rest your hands on).

For regular computing science, 8GB would be okay. And I mean... just okay. You might run into limitations here and there but a good CS department in my opinion should have a remote server you can use for running very demanding test scripts, etc. I'm in my 5th year and I'm still using a laptop with 8GB of RAM. That being said, because you're doing informatics, I would air on the side of caution and get something that you can add more memory to down the road. 

I wouldn't risk it.
I started college with an 8GB laptop and it worked fine, for 1 year.
Second year, had to get a different laptop because mine couldn't be upgraded to 16GB and 8GB was just not enough anymore. It solved a lot of problems for me and never had issues for the rest of my education. (well, i did, but those were my fault, not the laptop)
 
Both were second hand btw. don't know if that matters?

This is a 3000 euro build, and the GPU may be overkill for you, but it is also a done deal in terms of future proofing.
 
So if you decide you want 1440p in newer more demanding games or even 4k in the games you mentioned, then you can make that switch.  I also think this machine would likely let you edit that footage quite smoothly too.
 
The only things I changed from the previous suggestion was the MB and GPU, motherboard only because I have heard great things about it, and the ASUS Prime Pro, I don't have any knowledge of, so didn't want to put that in as a recommendation.

Also, I left out the graphics card as I thought an RX 590 would be enough for the games you mentioned, but if you feel like you also need to upgrade that, something like a 5700XT or RTX 2070S would be solid upgrades over the 590 for 1440p.
I also wasn't sure whether you needed more than 32GB of RAM or not, but if you do you can bump that up to 64GB with no problems.

then it's the cpu you need to upgrade. consider a 3900x

You can download HWMonitor for free from CPUID (?) just google it, it will show you what your machine is doing under load.
 
That would probably tell you where you need to upgrade a little.
 
From first look, RAM and GPU are obviously not high spec, so they would likely be areas for improvement.  Going to 3600 mhz RAM may have an impact, and upgrading the GPU may have an impact and if you are working and it is affecting productivity then you may not want to wait.
 
However, it is money down the drain if that is not where the bottlebeck is occurring so see where your issues are first.

that is the cleanest way to install it, just remember to enable nvme and not sata in bios, and put it in an m2 port that supports pcie. 
Disconnect the current disk so it don't try to boot from it. or accidently delete the partitions. 
 
to find the media and install guide use this link https://www.windowscentral.com/how-create-windows-10-usb-bootable-media-uefi-support
 
Download the correct drivers before you start install. put them on the install USB, or a USB you can have handy for the install.
Do not enter license key, just log in with your normal user if you have it online enabled. it should manage to reactivate then. 
after installation you can connect the old drive and start moving things over to your new drive. 
 
Most games installed from steam uplay etc, you can install the client program and search for installed files so you don't need to download everything again. 
 

I used a software called Data Migration Tool provided by Samsung to move all the files and Windows to my new 860 EVO 1TB. It's been two months now, there's no problem so far. You can try it.

Even now, the R 3500 CPUs are decent and not too expensive, but if you can wait, the old ones will become cheaper. What is your budget ?
