These are not PCs, and as such, the chips on the board are quite old, and replacement parts are going to be a trick.
Add to that, they went through several versions internally, so finding main chips to swap out may not even work, plus, I really hope you are good with a soldering iron.
 
Having said that, mainboards exist on ebay for cheap, if you wanna have a learning experience...
 

Are you looking to upgrade your RAM to be smart home compatible? Do you want RGB lights so bright that they blind you? Then these Philips Hue LED Lightbulbs may be the upgrade solution for you!

I wonder if Intel are currently trying to figure out how to fit a water chiller onto a laptop 🤔

Update from XMG:
 
Summary:
In typical gaming laptop fashion, the 4900HS has already been dethroned by a more powerful laptop, the XMG Apex 15 featuring a full desktop Ryzen 9 3950X.

My Thoughts:
STOP STOP. THEY'RE ALREADY DEAD. It looks like high-end laptops are getting extremely competitive this year and I am more than happy. Per derbauer's own graphs, the R9 3900X is 44% faster than the 4900HS, it'll be interesting to watch the gaming and professional laptop space the rest of the year and onwards.

You can buy some already finished, here were i lilve there is a lot of business that will sell you the finished product, some with a computer and some without for a cheaper price.
 
I built my first arcade cabinet with an X-arcade tankstick, several wood planks for the cabinet, a 32 LCD tv, a Raspberry pi 3, two car speakers, and so on.
 
After having everything working and playable i started changing stuff,.Like for example the amplifier in the PI i changed it to a HIfiberry amp2, the sticks of the X-arcade i switch them for two sticks from the brand I-Lorenzo, changed the RPI3 to a RPI4. 
 
Now i want to modify or build the Wood cabinet again to a different style because it is too big for my new apartment but i don't have the tools or the space so i will complete the cabinet in my dad's house. 

Yeah, it should be fine. The original power supply is designed to run it with accessories and yours should be close enough to spec that it would be fine.

Actually, just go with the AX200 out of these options. It supports the newest Wifi standard and isn't too expensive.

Not much point in playing stump the teacher.  Neither the teacher or your classmates will be impressed.  Usually when someone is asking the teacher a bunch a questions beyond the scope of the class and wasting everyone's time it is not looked favorably on.

@RorzNZ Are any of those even related to computer science?
 
Also to OP: Trying to make your teacher's life difficult is not the answer to whatever problem you have with him. Just finish the class and move on.

The Dell S2719DGF is a TN panel that is pretty good and reliable. If you want an IPS monitor, you could try the BenQ EX2780Q. It's only 20 pound over budget. Heard it's really nice but do not use HDR as it's only HDR400 and looks horrible. Also, this next monitor is out-of-stock online in the UK but if you can find it for anywhere around 380-420 pounds (might have to check local stores), the LG 27GL83A would be a better choice than the BenQ.

Granted Skylake and it's many, many derivatives have been good architectures for a while, but this is really starting to look pathetic. Not nearly as bad, but comparable to AMD's shitty FX refreshes that inched performance upwards in exchange for workstation-class power draw.

It's not every day you see a wireless optical keyboard with RGB, but here we have one. The Keychron K4 is a 96% keyboard priced at under $100 depending on the configuration you get, but there's no reason to write it off because it's cheap. Over my week of using it, I have found some quirks I like about it, but there's also things not to like about this board. The standout feature is that it's offered with optical switches by LK, a type of contactless switch, along with traditional contact-based Gateron switches. Mine is configured with the Blue variant of these optical switches, as well as a plastic frame and RGB lighting; altogether, it came to $90. Without further ado, let's get on with it.
 
A lot like the Hexgears Impulse I previously reviewed, the Keychron K4 is pretty no-frills. It comes with rather thin, laser-ablated ABS keycaps, which do not feel very great, but they are shine-through. There's also no ugly "gamer" font, so thanks for that, Keychron! This is a 96% keyboard with 100 keys, so compared to a traditional full-size keyboard it's more compact, albeit missing some nav cluster keys. Well... actually, it's more of a 99 key keyboard, because Keychron for whatever reason puts a dedicated backlighting key in the upper right corner. This key does nothing but change what backlighting pattern the keyboard is using. As a result, the home, end, pgup, pgdn and delete keys are shifted over a key, and the print screen key is deleted. I do not like this, as I found this key rather useful for allowing me to be precise with what I screenshot.
 
Now, you might be saying "Oh, you can just program the missing keys onto layers!" to which the answer would be... no. There's no official software from Keychron for this keyboard. Instead, they include a slip in the box that tells you that if you want to remap your keyboard, you need to download this third party software, the Windows version of which depends on Registry hacks! No thanks, especially since I'm one of those nerds who owns more than one keyboard.
 
Perhaps most bizarre though is where the USB port is. It is Type-C, which is very nice to see, but unlike most other keyboards where the USB port is on the back, the USB port of the K4 is on the side. Not wanting to risk breaking my only USB-C to -C cable, I bought a right angle USB-C to -C adapter to reduce the stress put on it.
 

 
Perhaps mercifully, Keychron includes a right angle USB-C to -A cable in the box, but I found it too short for my desk setup.
 
Due to the lack of dedicated software, there isn't much in the way of RGB customization. You can hit the backlighting button to change between 18 presets, and then use the Fn key + left and right arrow keys to swap between colors, but... compared to what I can do with a keyboard with dedicated software, it's pretty limited. The backlighting does look nice and vivid though, and running a preference poll between this board and the similarly-sized Input Club Kira on Twitter resulted in me learning that people prefer the way how the lighting on the Keychron K4 looks.
 
As for the switches, these are a type of contactless switch, as in there is no contact leaf used to register a keypress, a la most keyswitches. Keychron says these are rated for 100 million keypresses, but in more accurate terms, tens of thousands of hours, due to the limiting factor being the lifetime of the optical sensors rather than the switch mechanism, which simply consists of a plastic slider and spring. If you need more on how these work, the spring blocks a laser from an infrared LED, and when pressed the slider allows the laser to shine through to a receptacle, which then registers the keypress and sends it to the computer. Being that these are optical, they are insanely quick to respond, with Keychron stating that their response time is only 0.2 miliseconds. However, these switches are very light, and I often found myself making mistakes when typing. It actually put some strain on my fingers the first time I tried using it! If this isn't up your alley, the K4 does come with a choice of four Gateron MX clone switches: Blue, Brown, Red and Yellow. This reduces the price by $10, so you are paying a bit of a premium for optical switches over traditional contact switches.
 
I got mine with the clicky variant of the optical switches, but I can't seem to figure out what makes them, well, click. I can't find any evidence of a click bar in them, a la Kailh switches, nor can I find a more traditional click jacket in them. There probably is a click leaf in the assembly, which would ruin the point of a contactless switch, but if there is I can't feel it. The click isn't very strong and easily gets overshadowed by the sound of the keycaps clacking and the insane amount of ping. I don't know if my board has bad springs or what, but the springs are very pingy and sometimes squeak a bit. Keyfeel is very smooth regardless, but if you aren't a big fan of ping, this is not the keyboard for you.

Also, it's worth noting that contactless does not mean guaranteed smoothness; there are enough Soviet-era keyboards floating around to disprove that theory.
 
Now as for another headlining feature of this keyboard, Bluetooth connectivity! At least on my PC, this seems to be a mixed bag. A lot of the time it works pretty great, but there are times when the signal gets weak and the keyboard begins inputting wrong, repeating characters or missing them altogether, with output on my computer delayed. Not great, guys. However, the keyboard comes with an integrated 4000mAh battery, which does last a good few days before you need to plug in the keyboard again; Keychron estimates up to 70 hours working time with Bluetooth and RGB lighting enabled. If you disable the backlighting, which can be done by pressing Fn + the backlighting key, this gets extended to 4 weeks. Damn son. Also, unlike the Anne Pro 2, wherein you could only have it plugged in or wireless, but not both, the K4 allows you to have it plugged in while using it wirelessly. Switching between wired and Bluetooth modes is quick and easy, being done with a switch on the side.
 
Speaking of switching modes, by default this keyboard is configured for MacOS, but for Windows and Linux users, reconfiguring the board for non-Apple operating systems is as easy as swapping a few keycaps on the bottom row and moving a switch also on the side, right below the USB port. As mentioned before, this keyboard comes with laser-ablated ABS caps, but what I didn't mention before is this keyboard is MX-compatible, even with optical switches. Keycap replacement will be hard, though, due to the non-standard layout and most aftermarket cap sets that don't cost over $100 being designed for a standard ANSI/ISO 104/105 key layout. If you wish to get some aftermarket caps, be prepared to spend at least $100 on a GMK set as I can't find much else that will fit on this keyboard, or many other 96% boards for that matter.
 
As for ergonomics, this keyboard is both great and not great. While the 96% form factor saves room on your desk compared to a traditional full size keyboard, this is a very high profile keyboard. The caps are OEM profile, rather than something smaller like Cherry profile, and with the flip-out feet up, it has an 8.5° angle. The rather steep profile required me to use a high profile wrist rest to avoid straining my arms as well as my fingers, so keep that in mind. Without the feet flipped out, the keyboard assumes a 0° angle, but, again, it's rather high profile. You will need a wrist rest to comfortably use this keyboard.
 
So, after about a week of use, how do I feel about the Keychron K4? Well, considering the features you get for the price, I do feel it offers a lot of value for your money, and the optical switches do provide it even more if you're a hardcore gamer. However, the Bluetooth performance, at least in my case, left a lot to be desired, and the horrible pinging can get maddening over longer typing sessions. Also, the rather high profile strained my fingers, which made longer typing sessions uncomfortable, especially for my bad right arm, and the light optical switches led to me making more mistakes than usual when typing. However, the Bluetooth mode is nice to have, and if you're a Mac user, this keyboard does come configured for it by default. Perhaps if you're looking at using a keyboard other than the terrible keyboard Apple usually includes on their laptops now, you could look into this board, just saying. Considering this comes in below $100 though, for the features you get it's hard to complain, but there are some things that left me wanting better from Keychron. Perhaps switching to lower profile caps, using heavier springs in the optical switch variant and including a second, less extreme angle for height adjustment could go a long way towards improving ergonomics.
 
Anyway, thank you for reading. No typing recording this time, but to give an idea of what it sounds like, you can hear a bit of it in this tweet of mine. I'll probably write a few more keyboard reviews in the future as I have some ideas for what I want to check out, but in the meantime, I wish you guys a nice 2020, and may you get some decent keyboards this year.

Sometimes older drivers can cause issues, but this shouldn't be too common. Just try running your system as-is and see if you have crashes or weird behavior. If you do, then you can try running Display Driver Uninstaller (DDU) and installing fresh drivers. But in general the drivers should be fine. You can even use Nvidia and AMD cards together in the same system if you really wanted to, but this wouldn't be practical for gaming. 

Hmmm, your brother doesn't seem to know what he is talking about.  Like . . . at all.

A lot of bad information overall in this thread.  
 
1.) You cant go Quad Channel with Ryzen 3000 (or Intel consumer products afaik)
2.) Single Channel (1 stick) is performance degradation on both platforms
3.) Almost all of AMD product line-ups are overclockable, highly recommended from me
4.) Your brother has no idea what he is talking about
5.) A iGPU (integrated GPU) will only work for doing Netflix and stuff.  Some games like Pinball will work fine with it but overall its not a GPU (built in graphics display on intel).  If you are not building a gaming rig, then go with AMD APU's, still a much better offering than Intel atm.

The only thing AMD processors don't have yet is AVX 512 support.
 
Which is useful in like 0 consumer applications.

R5 3600 is overclocable just like all other AMD CPUs, AMD is not doing the same locked shit the Intel does. All the X at the end means is just that it's slightly better binned CPU factory pre-overclocked a bit.

I suggest you stop talking to your brother about computers.

in my book, thats 95$ more to spend on a GPU

If i were you, i would probably go with AMD

Wait the R5 3600 is 95 dollars CHEAPER than the i5 9600K?
 
You're literally buying a superior/better product for cheaper this is a no brainer, the R5 3600 is the obvious take in here.
 
You should always use dual channel memory as single channel memory will cripple your system performance.

I don't know about the processors, but I guarantee that you'll want to stick with dual or quad channel RAM
 
Edit: The i5 that you picked was overclockable and the R5 3600 isn't. The R5 3600X is overclockable. But that may not matter to you.

He's giving you some BAD information. First, you should always go with dual-channel RAM if it's an option. Single-Channel immediately takes away performance. Second, you cannot use Intel's integrated graphics to play any real games. You need to purchase a GPU no matter what. Finally, the Ryzen 5 3600 offers better overall performance, but it does lose in a handful of games. 
 
So you had the right idea, do not listen to your brother.

If you have to look in your pants, you aren't very secure. ?
This points out a failing with most of these kinds of surveys: they are based on many sterotypes, limited assumptions, cultural difference, etc. For example, nowadays, sewing clothes, etc. is considered a feminine activity yet, once upon a time, only men made clothes (with the exception of women's undergarments; that was done by women). 
 
I avoid these surveys and tests because of this and that they usually are used for personal data harvesting.
