How to construct your mini-ITX gaming PC

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

Everyone hates manuals, however for a PC construct they’re important. Particularly the case and motherboard handbook, so, maintain them helpful and let’s get into it.

Installing the CPU

Installing the CPU may be nerve-wracking because it’s an costly and fragile little factor, however it’s really very straightforward to do.

First, elevate the little steel lever by pushing it gently to the facet 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, ensure to not twist it in any respect and also you should not want to use any pressure. Once it is correctly seated, decrease the lever and tuck it again below its retention tab.

That wasn’t so unhealthy, was it?

Installing the RAM

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

Begin by releasing the latches on all corners of the RAM slots. Then, align the reminiscence follow the notch within the slot, it will probably solely go in a technique round.

Once you are assured it is in the fitting place, apply agency and even strain to the highest of the RAM stick. You ought to hear a satisfying click on because the latches snap into place.

Finally, double-check that every one the latches are secured earlier than transferring on.

Installing the NVMe SSD

We’ll be utilizing the M.2 slot on the rear of the motherboard for our SSD, as it’ll permit us simpler entry for later upgrades. However, if you’d like further cooling, we would suggest utilizing the cooled mount discovered on the entrance of the motherboard. Either means, the method may be very related.

Once 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 technique round. Usually, the SSD’s brand shall be going through outwards.

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

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

Preparing the case

The H1 case may be very distinctive in its building, however NZXT has carried out an incredible job in clearly marking issues to make it as easy as may be.

To entry the internals, pull off the glass and rear panels by lifting from the marked space on the backside. It can take a little bit of pressure the primary time it’s carried out.

Once eliminated, you’ll be able to slide the steel shell upwards and off of the chassis, supplying you with 360-degree entry to the internals.

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

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

Remove the 2 screws on the high of the panel, then the radiator can fold out of the way in which.

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

Installing and connecting the motherboard

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

In this case, we wish the IO protect going through in the direction of the underside of the chassis, which is an uncommon configuration. Normally, the IO protect would go in the direction of the rear of the case.

Simply align the motherboard with the 4 standoffs, one shall 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.

Next, we have to join up the ability provide, fan and entrance panel connectors. We will not go into an excessive amount of element right here, it is a fiddly job however every little thing is labelled clearly. Consult your motherboard’s handbook should you get caught.

The H1 case takes numerous the effort out of this step by having the cables routed to the proper location and at roughly the proper size. It’s only a case of matching them up and connecting.

If you have got any cables left over, don’t be concerned, not all cables shall be relevant to all builds. For our construct, we did not have wherever to attach the USB 3.1 entrance panel header, that means that the USB-C port on high of the case will not work except we purchase an adapter. Just be sure you tuck it neatly out of the way in which and it will not trigger some other points.

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

Finally, use the velcro straps to tuck your extra cabling out of the way in which as neatly as potential. This is particularly essential within the H1 as we can’t have a lot clearance between the radiator fan and the motherboard as soon as assembled.

Installing 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’s finest to pay shut consideration to the H1’s handbook with a purpose to choose the proper components, however we’ll be needing some screws, clips and a bracket.

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

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

Carefully, place the CPU block over the CPU and fix the retaining clips to the plastic hooks on the motherboard.

Tighten the screws down along with your fingers at first, then seize your trusty screwdriver with a purpose to make them comfortable.

Try to use even strain on the CPU by tightening either side a few turns at a time.

Once 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.

Once it is in place, reinsert the 2 screws we eliminated earlier.

Installing 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’ll be able to in all probability do that by hand, however use a screwdriver if they seem to be a bit stiff.

Then, find the PCIe energy cables on the high of the case and pull them out to the facet for straightforward entry.

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

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

Ensure that it is absolutely seated and that the latch clicks into place.

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

Once 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 with a purpose to see what we had been doing.

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

Putting it again collectively and testing it out

To reattach the panels, first, slide the steel 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 can then plug in an influence cable, a monitor and peripherals – and pray that we did every little thing accurately.

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

Installing Windows
