To begin with you should gather all the necessary parts for a PC, as listed below.

Note: You might be thinking that the supplies are missing a GPU, but that is because the CPU has integrated graphics, but if you do have a GPU there will be instructions on what to do with it.

Supplies

Ram stick

MDOT drive

CPU: Intel Core i3-8100

Power Supply

PC case

CPU cooler

Mother Board

I/O Shield

Screw Driver (not shown)

PC Case Screws (not shown)

Stand-off Screws (not shown)

MDOT Screw (in tiny bag)

Monitor (not shown)

Video Cable (not shown)

Step 1: Hook Up Power-supply

Before we do anything with the case, we first have to see that all the parts work properly, and to do that we've got to connect all parts to the motherboard outside of the case. But first that means taking the Mother Board and power supply out and hooking them up to each other. The 20/24 pin connector on the power supply hooks up to the longest hook up on the board, which coincidently has 20/24 pins. Next you would hook up the 4/8 pin connector to the hook up closest to the CPU, which, funny enough, has 4/8 pins. If you have a GPU(graphics card) then you would find the 6/8 pin connector and put it in the 6/8 pin hook up, if there are two 8 pin hook ups, use the one furthest from the CPU.

If you're having trouble differentiating the CPU and GPU connectors, a lot of the time they are labeled.

Step 2: RAM and MDOT

Next we'll do the simple stuff, there should be two close together, long slots, usually next to the CPU with a physical barrier in the slot, that is where you insert the RAM, make sure the divot in the RAM stick lines up with the barrier in the long slot, otherwise it won't go in (a keyed connection).

The second half of this step can be hard, the MDOT drive has to be inserted in another slot with a keyed connection. This is usually located near the edge of the motherboard, and unlike the rest of the slots it is a stout, flat, and doesn't stick up much. When the MDOT is inserted it will stick up like hair in the morning, so we have to lay it flat and put a extremely small screw in the hole on the motherboard that lines up with the indent in the drive. Exercise much patience when doing this because if you drop that screw it can be very hard to find. Once the screw is in enough to stay in there on it's own, you grab a small Philips head screwdriver ( or just the bit) and screw it in the rest of the way, not too tight though, that's bad.

Step 3: CPU and CPU Cooler

This step can be kind of a pain sometimes. The CPU socket is usually located in the upper-middle part of the motherboard, it's hard to miss. Regardless if you have an Intel or AMD CPU, you must NEVER push down on it when you put it in. Gently wiggle it back and forth until it sets in, then lower the socket over it again and latch it.

Next comes the cooler, usually you need to put thermal paste on the CPU before you do this, but some coolers come with thermal paste already applied. When attaching this make sure that the heat sink part is touching the CPU, with thermal paste in between. Then you shove the little tabs through the holes in the motherboard, you may have to try screwing them in too. But if you do shove them in, be prepared to use what feels like an unreasonable amount of force. There is a cable that comes out of the CPU fan, you want to hook that up to the 3 or 4 pin that is labeled "CPU_fan".

Some CPUs have a bracket for the cooler, if yours does then just put the cooler on top, same as before, and then latch it in there with the provided latches, also may require a lot of force.

Step 4: Monitor and Test

Now that you have everything on your mother board, hook it up with the appropriate video cable to a monitor and see if it works. If you encounter an error screen, make sure everything is plugged in, plugged in the right spot, that your pins on the CPU are all right, etc..

Step 5: Case Time

Now, take off all the Power Supply connectors and prepare your screwdriver. To put the motherboard in the case you first have open the case, bonkers, I know. The front panel is what we want off right now, usually this panel is on the left side when facing the front of the case, also if you have a plexiglass or clear plastic side, it's that side. These screws usually have rivets and divots and a big head, unscrew those, then take off the panel. Next you'll put the I/O shield in the long rectangular hole in the case, this is where all the back panel stuff on the motherboard goes through.

Now you'll see a bunch of small pillar looking things that have holes for screws to go into, this is where you insert your standoff screws through the holes on the motherboard (these holes have shiny things surrounding them). Based on the form factor of your motherboard you have to insert them in different spots, don't worry, the case gives you a key so you know which ones to use. To make this process easier on your fingers and patience many cases come with a little silver tool that has a spot for a Philips head screw driver, this is used on the standoff screws to screw them in easier.

Note: putting the motherboard's back panel stuff through the I/O shield first can make lining up everything else easier for you.

Step 6: Putting in the Power Supply

Now you'll have to take off the back panel, if you need help finding it, it's the panel you haven't taken off, provided you did the last step correctly. there should be a cubby hole that's about as thick as the power supply. When inserting the power supply make sure that the fan is facing the grating, and that the screw holes line up with the holes on the case. Speaking of those holes, now it's time to use somewhat small screws to secure the power supply to the case, there should only be four screw holes on the power supply and it's pretty straight forward on how to screw them in.

Step 7: Hooking It All Up/ Cable Management

Now you have to connect all the power supply connectors to the motherboard again, the only difference from last time is that it's all in a case, so now you have to thread the cables through the panel in the middle that separates the front and back. For cable management's sake you usually don't want wires/cables crossing over the entire motherboard, so avoid that if possible. For the extra cables you can group them together and stick them somewhere where there's room, or you can just shove them all in the space with the power supply, your choice.

There are a few extra wire you need to hook up, first and foremost being the front panel connectors, the pins for these are all on the edge of the mother board and conveniently labeled as to which is which, though it can be an annoying process because of the angle that you have to try to put them in, so you may want to lay your computer on its side. The case fan also has to be hooked up to the mother board, it hooks up to the 4 pin places on the edge opposite labeled "sys_fan1" and "sys_fan2", I recommend connecting to the one that doesn't have your wires cross over the CPU fan.

Step 8: Make Sure It Works

Now you hook it all back up to your monitor and see if it doesn't give you an error screen, if it does remember to see if the power supply is on, it the red switch is at the right voltage, if everything is plugged in right, etc..
