How much does a computer case cost?

Computers cases serve a crucial purpose in securely housing your components, keeping out dust, liquid and other contaminants. A PC case helps protect components against other conductive elements which can short circuit and wreak havoc. While all cases carry out this important role, they vary considerably in price, size and style in accordance with your needs and specifications.

Mid tower ATX cases are by far the biggest, most readily available case size, so there's some competitively priced and budget-focused options available. The sheer, hulking size of Full Tower E-ATX cases make them a niche choice - double check you've got enough space to spare - so you'll be paying a premium for the extra material. Conversely, small form factor Micro ATX cases and Mini ITX cases are exploding in popularity for their space-saving footprint and compact aesthetic. They'll likely be cheaper than a full tower case, too!

If you're looking for a basic, no-frills cases to, you might opt for one of our budget chassis, which start from as little as £20. If you're building an all-out gaming PC with power-hungry parts, Ebuyer also stocks a great selection of high-end PC cases in a wide variety of shapes, sizes and designs. These cases are a perfect choice if you want something more sophisticated, as they comfortably house gaming-grade components to ensure optimal performance.

What comes with a PC case?

While you'll have to purchase your PC parts separately, most computer cases have at least some convenient extras pre-installed.

This might include a sheet metal shroud for the power supply and the storage drives, hiding their cable clutter. Some cases even come equipped with the power supply unit itself - use the handy filter on the left to find these bundle deals.

As well as this, the most common inclusion you'll find are case fans. These draw in fresh air from outside and exhaust out hot air, helping keep your components cool. Wondering how many case fans you need? Check out the 'read more' section for PC cooling and modding, here…

It's important these parts don't interfere with your existing components, so check the specifications and dimensions of your system.

Computer case form factors

To find the perfect PC gaming case or computer case for building or upgrading your PC, you can filter by size using the subcategory feature on the left-hand side of this page.

Full tower cases

As the largest type of computer case available on the market, full tower cases are both impressively weighty and sizable. Exact dimensions vary greatly between brands, but you'll be looking at a case around 24 inches tall with a similar or even greater depth. Due to their looming, monolithic size, full tower cases easily support all motherboards with an ATX form factor, which maxes out at 12 by 9 inches - even extended ones.

This leaves you plenty of spare room to figure out a cooling solution, whether it be an intricately laid out water cooling loop with radiators, pumps and reservoirs, or a cohesive air-cooled set-up with tons of fans and adequate clearance for humongous CPU coolers.

One of the biggest attractions to full tower cases are their expanded selection of storage drive bays. On smaller cases, these bays are typically reduced or outright removed. Whereas on a full tower case, you'll have room for stacks and stacks of hard drives and solid-state drives.

If you're compulsive data hoarder, create regular back-ups or host your own server, you'll revel in all the space a full tower case affords. Especially if you're stickler for physical media - full tower cases are clinging onto front accessible bays for internal Blu-Ray and DVD drives.

Mid tower cases

As the most popular category of computer cases by a significant margin, our broad range of mid tower cases give you an extraordinary amount of choice. Competition's high, so you'll find mid tower cases starting from as little as £20.

As their name strongly suggests, they're manageably sized PC cases in-between a full-sized tower and a small form factor case, often cited as the sweet-spot in regard to ease of installation, access to components and airflow.

You'll be looking at a case around 18 inch tall with a similar depth, while still supporting full-sized ATX motherboard. This is what makes mid tower cases so broadly appealing - they're fully featured like full-sized cases, without consuming a cumbersome amount of space. You might sacrifice some expansion slots, but for the average set-up, they're more than adequate.

Factoring in their price tag, size and features, mid tower cases make an ideal entry point of first-time PC builders.

What should I look for in a computer case?

Everybody's got their own personal preferences when it comes to PC cases, but here's some key features to keep and eye out for while browsing our broad range of cases.

Airflow

A computer case's airflow is easily of the most crucial considerations. You'll want plenty of perforations acting as intakes and exhausts for the case fans. Otherwise, you're trapping your components inside a hot enclosure. They'll suffocate on their own stale air and thermal throttle to prevent damage, affecting performance.

For a gaming-grade rigs, the latest trend is fine mesh panels reducing restrictions for maximum airflow. Cases completely decked out in tempered glass are eye-catching, but you've got to ensure airflow's coming from somewhere.

Dust filters

The main disadvantage of increasing airflow is the subsequent presence of dust and other contaminants. It's unavoidable, but somewhat preventable with the right measures. Many computer cases come with dust filters situated in front of the fans to catch most stray particles sucked in by the fans, instead of clogging up components.

These dust filters are often mounted magnetically for easy removal and routine maintenance. If you place your PC case on dust-attracting carpeted flooring or if you've got fluffy pets, dust filters are must-haves.

Front panel I/O

While your motherboard and graphics card feature an overwhelming abundance of ports for hooking up monitors, keyboard and mice, your computer case's front panel I/O comes in clutch for effortlessly plugging in other peripherals, rather than blindly fumbling around at the rear of the PC case. USB-powered external drives, memory cards, smartphones, headsets and more - ensure there's enough ports for your needs.

Component dimensions

The trickiest part of picking out a computer case is ensuring all your components will fit properly. If you haven't already got the components in your possession, it's difficult to visualise how everything slots together. It will require stringent cross-referencing with other product's spec-sheets, as well as accounting for the thickness of extra cooling equipment.

The top three dimensions you'll need to check are the CPU cooler height, graphics card length and power supply length. Fortunately, many PC case manufactures included these right in the product's description. If you're building in a small form factor Micro ATX or Mini ITX case, be acutely aware of their extremely tight margins.

Cable Management

What makes a great computer case stand out against a bog-standard one is an organised layout to neatly route cables, minimising clutter. Hooking up to other components, your power supply's cables can spawl uncontrollably if not managed properly. Messy, loosely hanging cables will impede airflow, make future upgrades unnecessarily confusing and be a distracting eyesore.

Look for PC cases with optimally placed cut-outs for the shortest cable runs possible, rubber grommets on sharp edges, cable tie-down spots, PSU shrouds and other cable management features.

Transparent side panel

Purely aesthetic with no performance impact, transparent side panels are computer case essential for those wanting to show off their system's specifications, RGB lighting and cable management expertise.

These PC case panels used to be constructed from plastic which scratched and scuffed up easily. Now, even the cheapest cases have transitioned to beautifully clear tempered glass, giving your case the sleekest, uninterrupted look. Or, if you'd rather a stealthy, unassuming case, there's cases available with no-frills sheet metal panels.
