Cases & Modding

Lian Li PC

Overclockers UK sells an extensive range of cases from a wide range of manufacturers. We cater for all sizes, shapes, requirements, and personal tastes. Whether it's fitted with RGB lighting, built with an aluminium chassis, or optimised for silent operation utilising the latest noise-dampening technologies.

For many PC gamers, building a custom gaming rig is as much about the performance as it is the aesthetics. It's more than just a shell holding their components – it's a demonstration of craftsmanship, skill, time, effort, and personality.

From the large copper heatsinks resembling a Supercharged 69 Camaro, to the custom watercooling set-ups which adopt the visual traits of a futuristic chemistry lab – PC enthusiasts take pride in their builds and will stylize their chassis to emphasise their internal component choices.

Case Form-Factor

When buying a PC chassis it's important to make sure the motherboard form-factor is compatible. Here we take a look at the main ones:

Mini ITX case


Ideal for building a PC of the smallest physical size while still being able to support high-end hardware – the Mini ITX form factor gives way for cube and game console size builds, proving that towers are simply a matter of preference as opposed to being a requirement.

Micro-ATX case


Only slightly larger than the Mini-ITX sized form-factor, the M-ATX allows for larger and additional hardware such as dual graphics cards, an increase in storage drives, and more flexibility for watercooling setups. Cases within the M-ATX form-factor are available in cube, mini-tower, full-tower, and game console sizes.

ATX case

Standard ATX

Allowing support for larger hardware and extra graphics cards, with more options for cooling such as larger fans and watercooling equipment, the standard ATX size case features a greater range of styling and sizes, with some chassis being the same physical size as a M-ATX case – allowing the internal component layout to appear more compact. Should users want a larger case, the choices go even further.

ATX Full case

E-ATX Full Tower

Designed for use with standard ATX and E-ATX size motherboards, full tower cases vary greatly in size with some being only slightly larger than the standard ATX, while others being physically unable to fit atop a desk. As with all form-factors, chassis are all about preference. For the PC enthusiasts looking to build a rig fitted with dual or quad applied graphics cards, along with extensive watercooling and multiple radiators, the E-ATX full tower chassis proves to be the most versatile form-factor for compatibility.

Case accessories and modding

Now you have chosen your case - you need to accessorize and personalise your build. From LED lighting and side windows to fan controllers and dust filters, we have you covered. Lets take a look at the most popular case accessories and modification’s.

Case Lighting

LED Lighting Strip

Case Lighting has the ability to transform the entire look of the interior of a case. You can highlight particular areas or opt for an all-round glow. With the latest RGB lighting you can even add an extra dimension of interest thanks to the multitude of effects and wide array of colours that can be controlled on the fly. Most lighting options now come with a variety of adhesive options including magnets which will allow you to move the lighting to a more suitable location or even reuse at a later date. They are a cheap, easy to install upgrade and highly recommended.

Cable Sleeving

Cable Sleeving

Cables are normally a multi coloured ugly affair. With sleeved cabling you can completely transform the aesthetics - Turning those horrible cables into a visual masterpiece you are proud of. There are several ways to go about this of varying difficulties. The easiest option is to buy pre-braided extension cables which are suitable for your application or purchase specially made cables that are presleeved for your PSU. The other option is to completely sleeve everything yourself which is a challenge but it’s a marvel to behold when finished and you will feel a real sense of achievement.

Noise Dampening

Noise Dampening Foam

At Overclockers UK we sell a wide range of noise dampening foam which really reduces the noise emanating from your case. Its so simple to use - Peel of the backing tape and stick in position, that’s it! Just be aware that the foam can reduce airflow as it blocks the vents.

Fan Controller

Fan Controllers

These are the brains of your fan – Without a controller your fan will just spin at full speed unless you connect to your motherboard and setup the fan profile. Fan controllers coming in single bay, dual bay, or external form factors. Utilising a controller allows you to set the fans up how you want kicking in a specific temperature ranges. This ensures your system stays cool and quiet at all times.

Side Panel

Side Panels

If you are customising the interior of your case you want to be able to show off your hard work. If your case hasn’t got a windowed side panel as standard, we sell a wide range that will replace your old one allowing you to show off your style.
