Component guide

How to pick a case

PC case tiers explained, from showcase glass chassis down to a budget mesh tower, with what a case actually does to your temperatures and your noise, how much clearance to check before you order, and what the dual chamber layout is really for.

The short version

Buy the case last, after you know your cooler and your card, and treat it as three purchases at once: airflow, noise, and the only part of the build you will look at every single day.

The case is the component people choose first and should choose last. It is also the only one that is still on the desk in ten years, long after the card inside it has been replaced twice, so it is worth caring about in a way a power supply is not.

A case does three jobs. It decides how much air reaches the parts, which sets your temperatures and therefore your noise. It decides what physically fits, which quietly constrains every other decision. And it decides what the machine looks like, which is not a frivolous concern: a build nobody wants to look at is a build nobody enjoys owning.

How to pick

Answer these, in this order.

Each question narrows the field. By the last one there is usually only one sensible answer left, and it is often cheaper than where you started.

  1. What cooler and what graphics card are going in it?

    This is the whole question, and it is why the case is chosen last. A 165 mm air cooler and a 360 mm radiator and a 340 mm graphics card each have a clearance number printed in the case specification. Check all three against the parts you have already decided on, and treat those numbers as hard limits rather than as guidance.

  2. Is this machine going to be looked at, or does it live under the desk?

    Be honest about this before you spend on glass. A tower in a footwell gains nothing from three tempered glass panels and a fan wall, and it loses real airflow to them. If the build lives out of sight, buy mesh, spend the difference on the card, and enjoy the quieter room.

  3. How much airflow does the layout actually allow?

    Look for mesh at the intake, not just somewhere on the case. A glass front with a 15 mm gap at the edges is a restricted intake no matter how many fans sit behind it. Front or bottom intake, top and rear exhaust, and an unobstructed path across the graphics card is the layout that works, and it is worth more than any single fan you can buy.

  4. Where does the cable mess go?

    A dual chamber case puts the power supply and every cable in a second compartment behind the motherboard tray, which is why those builds photograph so cleanly. In a conventional case the same job is done with a shroud and about an extra hour of work. Both get there, but only one gets there without patience.

  5. What is the floor and the filter situation?

    A case with bottom intake on carpet will eat dust and lose airflow within months. Check that the filters pull out from the front or the top rather than requiring the case to be lifted and turned over, because a filter that is annoying to clean is a filter that never gets cleaned.

Every tier here is a real answer for a real person. Lineup reviewed September 2026. Prices shown are launch MSRP, which is a fixed fact. Street prices move, so every product links to a live search.

Halo

A display cabinet that happens to compute

Dual chamber, glass on at least two sides, and room for more radiator than any single machine needs. The case is the centrepiece and the parts list is built to suit it rather than the other way round.

Who it is for
The build is the hobby. You want people to ask about it, and you are prepared to spend on fans to finish it.
The tradeoff
Ships close to empty. The photographs that sold you the case include several hundred dollars of fans and radiators that are not in the box.

Lian Li

O11 Dynamic EVO XL

Halo

The showcase case the rest of the category is measured against. Dual chamber, glass on two sides, room for three 360 mm radiators at once, and a reversible layout so the motherboard tray can face whichever side of the desk you sit on. If a build is meant to be looked at, this is the frame it goes in.

Best for
A custom loop, a distribution plate, or a fan wall that is the entire point of the machine.
Watch out
It is enormous and it is empty. Budget another two hundred to four hundred dollars in fans and radiators before it looks like the photos, and measure your desk before you order, because this chassis is closer to furniture than to a tower.

Showcase layout with a signature detail

The pillarless glass corner, or a screen built into the panel. These are the cases that make a build recognisable across a room, and they are still sensible chassis underneath the feature.

Who it is for
You want the machine to be part of the room, and you have a desk position where it will actually be seen.
The tradeoff
Glass on more sides means one way out for heat and a deliberate fan plan rather than whatever the case came with.

HYTE

Y70 Touch

Enthusiast

A 14.1 inch touchscreen built into the corner panel, wrapped around a wraparound glass chassis that was already a good showcase case without it. The screen is a real display the operating system sees, so it can run temperatures, a music player, chat, or a wallpaper, and it is the fastest way to make a build look like nothing else on the street.

Best for
Streamers and desk-side builds where the machine is part of the room rather than under it.
Watch out
The screen occupies a USB and a video output, it adds a panel you now have to keep clean and calibrated, and none of it makes the computer faster. Buy it because the second screen is genuinely useful to you, not because it photographs well.

Lian Li

O11 Vision

Enthusiast

Three glass panels and no visible pillar in the front corner, which is the detail that makes a build look like it is floating in a display cabinet. Same dual chamber plumbing as the rest of the O11 family, so the cable work hides in the back and the front chamber stays a clean picture.

Best for
A themed build where the front corner is the money shot and every cable has to disappear.
Watch out
Glass on three sides means heat has exactly one way out, so this case needs a deliberate fan plan rather than the two fans it ships with. It also shows every fingerprint, and the reflections that make it look good in a photo make the screen behind it harder to read.
Form factor
ATX dual chamber

Midrange

Where most builds should land

Real airflow, enough room for a 360 mm radiator, and either a clean showcase layout or a front that does not look like gaming furniture. This tier is where the money stops buying temperature and starts buying taste.

Who it is for
You want a machine that looks deliberate, runs cool, and leaves the budget where it earns frames.
The tradeoff
You give up the very largest radiator combinations and some of the interior room that makes cable work effortless.

Fractal Design

North

Midrange

A walnut slat front over a mesh intake, which is the rare case that looks deliberate in a living room and still breathes properly. It is the standing answer for anyone who wants a machine that does not announce itself as gaming furniture, and it costs less than half of what the glass showcases do.

Best for
A build that has to share a room with people who did not ask for a light show.
Watch out
The wood front is the whole personality, and it is not for everyone. Interior volume is ordinary rather than generous, so plan the radiator before you buy rather than after, and the glass side version breathes slightly worse than the mesh one.

NZXT

H9 Flow

Midrange

The dual chamber showcase layout at a mainstream price, with a mesh top and a wraparound glass corner. It ships with enough fans to actually work out of the box, which is not true of most cases in this category and is worth real money once you price fans separately.

Best for
A first showcase build that should look finished on day one without a second shopping trip.
Watch out
The included fans are unlit on the base model, so an RGB build means buying them twice. The glass corner also puts the front intake behind a panel, so keep the top and rear exhaust honest or the graphics card recirculates its own heat.
Form factor
ATX dual chamber
Included fans
4x 120 mm
Radiator support
Up to 360 mm top and side

Value

Small, cool, and quietly well made

A compact chassis with a fan layout designed around the graphics card rather than around tradition. The right answer when desk space is the real constraint and the build still has to run a full size card.

Who it is for
Desk space is tight, the machine sits on the desk rather than under it, and it still has to take a full length card.
The tradeoff
Clearance numbers are real limits rather than conservative estimates. Measure the cooler and the card before ordering.

Lian Li

Lancool 207

Value

Two 140 mm fans mounted in the floor blowing straight up at the graphics card, which is an unusual layout that works far better than it reads. It is a small case that cools like a bigger one, and it is the cheapest way into the Lian Li build quality that the showcase cases are known for.

Best for
A compact desk build that still wants a full size graphics card and quiet temperatures.
Watch out
The bottom intake sits close to the floor, so on carpet it eats dust and loses airflow. It is also a genuinely small interior: measure your cooler and your card before ordering, because the clearance numbers are real limits here rather than conservative estimates.
Form factor
ATX, compact footprint
Included fans
2x 140 mm bottom, 1x 120 mm rear
Intake
Floor mounted, straight to the GPU
Radiator support
Up to 360 mm side
Budget

Mesh, four fans, and nothing you do not need

The honest first build case. It will not impress anyone and it will keep a mid tier card cooler than a sealed glass box costing twice as much, which is the trade worth making on a first machine.

Who it is for
First build, fixed budget, and every dollar saved on the box goes into the graphics card.
The tradeoff
Thinner steel, more panel flex, and fans that are loud until you set a curve for them.

Phanteks

XT Pro Ultra

Budget

Mesh on the front, mesh on the top, four fans in the box, and a price that leaves the money where it belongs, which is in the graphics card. Nothing about it is fancy and nothing about it is wrong, and a first build in this case will run cooler than the same parts in a sealed glass box twice the price.

Best for
A first build, or any build where the budget should go to parts rather than to the box.
Watch out
The materials feel like the price: thinner steel, more flex in the panels, and a plastic front. The included fans are loud at full speed, so plan on a fan curve rather than leaving them on the motherboard default.

Airflow is a path, not a fan count

The number of fan mounts on a case tells you very little. What matters is whether air has a clear route from an unrestricted intake, across the hot parts, and out. Ten fans fighting each other in a sealed box move less useful air than three fans arranged in one direction.

The working arrangement is almost always the same: cool air in low at the front or the floor, hot air out at the top and the back. Run slightly more intake than exhaust so the case is at positive pressure, and the dust comes in through the filters rather than through every seam.

Glass restricts intake. That is not a reason to avoid it, it is a reason to plan around it: a glass fronted case wants its intake from the floor or the side instead, which is exactly what the dual chamber showcase cases do.

StyleWhat it is good atWhat it costs you
Mesh towerBest temperatures per dollar, simple to coolLooks utilitarian, fans are audible
Dual chamber glassShowcase views and effortless cable workNeeds a bought fan plan, larger footprint
Wood or fabric frontFits a living room, quiet by designOrdinary interior volume, less radiator room
Small form factorDesk space, portabilityClearance limits on nearly every part
None of these is wrong. The mistake is buying one style and expecting another style's strengths from it.

The four measurements to check before you order

Every case publishes these and almost nobody reads them until the parts are on the table. Graphics card length, CPU cooler height, radiator support by position, and power supply length. A modern flagship card is well over 330 mm long and three slots thick, and a dual tower air cooler is often 160 mm or more tall.

Radiator support is the one that catches people most often. A case that says it supports a 360 mm radiator at the top may not support it with thick fans, or with tall memory underneath it, or at the same time as a front radiator. Read the position, not just the size.

MeasurementTypical current partWhere it goes wrong
Graphics card length300 to 360 mmFront radiator or a front fan already occupies the space
Cooler height150 to 170 mmSide panel will not close by a few millimetres
Radiator thickness27 to 38 mm plus 25 mm fansFouls the top of the motherboard or the memory
Power supply depth140 to 180 mmCable bend radius, not the unit itself, is the limit

The case decides how loud the machine is

Noise is mostly a consequence of temperature. A case that lets the parts run cool lets the fans run slow, and slow fans are quiet fans. This is why a well ventilated mesh case is often quieter in practice than a sealed sound dampened one, even though the dampened one has foam in the panels.

The second source is resonance. Thin steel panels vibrate, and a case that flexes when you press it will hum at certain fan speeds. This is a large part of what the price difference between a budget and a midrange case actually buys.

Set a fan curve. Almost every complaint about a loud machine is a machine running the motherboard default curve, which ramps far harder than it needs to. That is a free fix and it is part of every build we hand over.

What makes a build look expensive

It is almost never the price of the parts. A showcase build reads as expensive because of four things, and all four are workmanship rather than components: no visible cable in the main chamber, every fan spinning the same direction with matching hub faces, one lighting ecosystem rather than three, and a colour palette with two colours in it instead of a rainbow.

The fastest route to a build that looks bought rather than assembled is a dual chamber case, a single vendor's fans, and custom length cables in one colour. That combination costs less than a graphics card tier step and changes the whole impression of the machine.
