Methods to construct your mini-ITX gaming PC

With any PC construct, and significantly on the subject of small type issue builds, it is best to get as many parts put in on the motherboard as potential earlier than putting in it into the case. Normally, this implies the CPU, RAM and NVMe SSD.

Everybody hates manuals, however for a PC construct they’re important. Significantly the case and motherboard handbook, so, preserve them useful and let’s get into it.

Putting in the CPU

Putting in the CPU will be nerve-wracking because it’s an costly and fragile little factor, however it’s truly very simple to do.

First, carry the little metallic lever by pushing it gently to the aspect and lifting upwards. Then align your CPU in order that the little golden arrow within the nook matches with the arrow on the bottom-left of the CPU socket.

Gently decrease the CPU pins into the socket, make certain to not twist it in any respect and also you should not want to use any power. As soon as it is correctly seated, decrease the lever and tuck it again below its retention tab.

That wasn’t so unhealthy, was it?

Putting in the RAM

On mini-ITX motherboards, that is simple as will be. Since you will be filling all of the slots, you do not have to fret about which stick goes the place.

Start by releasing the latches on all corners of the RAM slots. Then, align the reminiscence stick to the notch within the slot, it may solely go in a method round.

When you’re assured it is in the precise place, apply agency and even stress to the highest of the RAM stick. You need to hear a satisfying click on because the latches snap into place.

Lastly, double-check that every one the latches are secured earlier than shifting on.

Putting in the NVMe SSD

We’ll be utilizing the M.2 slot on the rear of the motherboard for our SSD, as it’s going to permit us simpler entry for later upgrades. Nonetheless, if you would like extra cooling, we would advocate utilizing the cooled mount discovered on the entrance of the motherboard. Both approach, the method could be very related.

As soon as you have positioned your M.2 slot, take out your screwdriver and take away the retaining screw.

Then, align the SSD with the socket, this too is notched and might solely go in a method round. Normally, the SSD’s brand will likely be going through outwards.

Insert the SSD at an roughly 45-degree angle, do not power something, it ought to go in fairly simply.

Push the SSD downward in order that it lays flat in opposition to the standoff, and re-insert the retaining screw to maintain it in place.

Making ready the case

The H1 case could be very distinctive in its development, however NZXT has finished an ideal job in clearly marking issues to make it as simple as will be.

To entry the internals, pull off the glass and rear panels by lifting from the marked space on the backside. It will possibly take a little bit of power the primary time it’s finished.

As soon as eliminated, you may slide the metallic shell upwards and off of the chassis, providing you with 360-degree entry to the internals.

Inside, you will discover an adjunct field, take away this earlier than persevering with.

To realize entry to the motherboard tray, we have to transfer the radiator. This too is clearly marked.

Take away the 2 screws on the prime of the panel, then the radiator can fold out of the best way.

Take each of the polystyrene blocks that safe the CPU cooler and take away them from the case.

Putting in and connecting the motherboard

This half is somewhat trickier because it’s the place the dimensions constraints of a mini-ITX case begin to come into play.

On this case, we would like the IO protect going through in the direction of the underside of the chassis, which is an uncommon configuration. Usually, the IO protect would go in the direction of the rear of the case.

Merely align the motherboard with the 4 standoffs, one will likely be positioned in every nook, and press the IO protect into its gap.

Then use the equipped screws from the case accent field to lock the motherboard to the case.

Subsequent, we have to join up the ability provide, fan and entrance panel connectors. We cannot go into an excessive amount of element right here, it is a fiddly job however every part is labelled clearly. Seek the advice of your motherboard’s handbook should you get caught.

The H1 case takes quite a lot of the trouble out of this step by having the cables routed to the proper location and at roughly the proper size. It is only a case of matching them up and connecting.

When you have any cables left over, don’t fret, not all cables will likely be relevant to all builds. For our construct, we did not have anyplace to attach the USB 3.1 entrance panel header, that means that the USB-C port on prime of the case will not work until we purchase an adapter. Simply make sure you tuck it neatly out of the best way and it will not trigger every other points.

Now we have to join our PCIe riser cable for the GPU. It is a lot like putting in the RAM, first, we now have to launch the latch. Then, line up the PCIe insert and press it into the slot till the latch flicks into place.

Lastly, use the velcro straps to tuck your extra cabling out of the best way as neatly as potential. That is particularly necessary within the H1 as we cannot have a lot clearance between the radiator fan and the motherboard as soon as assembled.

Putting in the CPU cooler

Slide off the bracket that comes fitted on the CPU block, we’ll be changing it with one which’s designed for AM4 motherboards as a substitute. 

It is best to pay shut consideration to the H1’s handbook so as to choose the proper elements, however we’ll be needing some screws, clips and a bracket.

Fasten the elements collectively as proven within the handbook and slide the meeting over the CPU block paying shut consideration to the orientation.

Fortunately, the CPU cooler comes with pre-applied thermal paste so we are able to get straight on with the set up.

Fastidiously, place the CPU block over the CPU and connect the retaining clips to the plastic hooks on the motherboard.

Tighten the screws down together with your fingers at first, then seize your trusty screwdriver so as to make them comfortable.

Attempt to apply even stress on the CPU by tightening either side a few turns at a time.

As soon as the cooler is secured, we are able to shut up the motherboard chamber by folding the radiator again up into place.

Take nice care to make sure that the CPU cooler hoses do not get pinched on something and that every one cables are away from the fan.

As soon as it is in place, reinsert the 2 screws we eliminated earlier.

Putting in the graphics card

Now we have to transfer round to the rear of the case to get the GPU put in.

First, take away the 2 screws on the backside, you may most likely do that by hand, however use a screwdriver if they seem to be a bit stiff.

Then, find the PCIe energy cables on the prime of the case and pull them out to the aspect for simple entry.

Launch the latch on the PCIe riser cable, simply as we did on the motherboard aspect, able to obtain the GPU.

Fastidiously align the graphics card with the PCIe slot and the slots on the underside of the case and slide it into place.

Be certain that it is totally seated and that the latch clicks into place.

Then we have to join the PCIe energy cables. We truly discovered this to be the trickiest a part of the whole construct, however these with skinnier fingers can have a a lot simpler time.

As soon as they’re in place, use the 2 screws to safe the rear of the graphics card to the case. We discovered it best to flip the case on its entrance so as to see what we had been doing.

And that is it, all of our parts are in. Time to see if it really works.

Placing it again collectively and testing it out

To reattach the panels, first, slide the metallic housing again over the body. Then, pop the back and front panels on by lining them up with the highest of the case and firmly urgent them into place.

We are able to then plug in an influence cable, a monitor and peripherals – and pray that we did every part accurately.

If it is all gone easily, you will see a satisfying illumination from your entire RGB clad parts and it is time to benefit from the fruits of your labour.
