Building your own PC is far more cost-effective than paying for one that's pre-built. However, for many, it's a daunting proposition, and it's easy to see costs spiral as you're planning out your parts. Opting for a budget PC case is one of the best ways to lower your overall spend, while still reaching those high benchmarks for your gaming rig or editing suite.
We've scoured the web for the 10 best budget PC Cases available on Amazon for under £100, so you'll be able to put those savings towards a top of the line graphics card and high-performance CPU instead. With ATX, Micro ATX and Mini ITX options available from big brands including Cooler Master, Corsair, and MSI, a premium build is possible even at a lower price point!

Making sure that it's compatible with your motherboard is by far the most important thing to check when buying a PC case. Most budget PC cases are designed with ATX motherboards in mind, as they are the most commonly found on the market today. Odds are, you'll be working with ATX motherboards which are around 30 x 24 cm in size, so don't be surprised to find that all but the smallest cases are compatible.

Micro ATX boards are a version of an ATX motherboard, containing much of the same architecture, but smaller in size at around 28 x 20 cm. Most Micro ATX motherboards will be compatible with the same cases as standard ATX motherboards.
On the other hand, Mini ITX are not always compatible with the same cases as ATX motherboards. Mini ITX motherboards are considerably smaller at around 17 x 17 cm and are used when making smaller form PCs. If you're working with a Mini ITX, it's worth investing a little extra into a smaller, specialist case rather than a budget option.
Once again, you want to keep your PC as cool as possible, and the best way to do that when looking at a budget build are fans. While liquid or water cooling may be tempting, it's complicated and only really necessary when seriously overclocking and aiming for the highest benchmarks. Realistically, water-cooling and budget cases do not go hand in hand.
Even the cheapest budget cases will have plenty of fans to keep your system at a comfortable temperature. Choosing fans and ventilation is a great way to keep your rig running smoothly during even the hottest summer months. The only downside is that the more ventilation your case has, the more dust can accumulate. If this builds up too much it can cause overheating, so make sure to regularly clean it!

All PC cases will have an open space at the back to plug certain accessories directly into the motherboard. However, if your tower is sitting on the floor or on a desk, reaching around the back to find the right socket or port can be incredibly frustrating - especially when you can't see what you're looking for!
You can expect to find several USB ports on the front of nearly all PC cases, and budget options are no different. So when deciding on the right case, think about how many USB ports you will need. Depending on your needs, you may also want to check whether it comes with 3.5mm audio-out ports for headphones, microphones and speakers.

Cooler Master are known as the premier manufacturer of heat sinks in the world, and their budget friendly case will have no problem keeping your equipment nice and cool. Representing incredible value, this option features 5 fans in total.
We particularly like the sliding front panel which keeps the front USB and audio-in ports covered when not in use. If you're looking for the best PC case at the lowest end of the budget spectrum, then you really can't do much better than this!
If you're looking to pimp out your build in the future, then there's no better option than the MSI Mag Vampiric. It's a solid choice when starting out, but becomes a great one if you're looking to invest in fans, lighting, or water cooling.
There's only one fan included, but it is RGB compatible. This means you can program the multicoloured lights to fit your overall aesthetic. If you require more, there's room for up to six fans and water cooling optimisation, making it one of the few budget cases that we'd actually recommend if you're looking for a liquid cooled build.
When it comes to computing accessories, there are few better brands than Corsair. So it's no surprise to see that their PC cases have the same high quality as their keyboards, mice, and other products. You'll be pleased to learn that this budget case looks and feels like a much more expensive option.
The frameless tempered glass side panel appears completely opaque while the machine is off, but when turned on, the programable RGB fans burst into life and illuminate the inside of your case. If you're eager to make a statement with your battle-station, then look no further!
This offering from Fractal Design features a large window that allows you to clearly see inside of your PC. We particularly like that it has extra space to route cables neatly behind the motherboard for easier cable management and a neater overall appearance.
While it only comes with two fans included, there is space for up to 6 to be installed. The filtered front panel protects the innards of the case from collecting too much dust, and the inclusion of two vibration dampening hard drive bays makes sure your data is kept nice and safe.
This small form case from Thermaltake is divided into two chambers. The first chamber ensures that everything is kept cool, which is always a concern when using in a smaller case, and is compatible with water cooling systems. The second chamber is for cable management, to maximise air flow.
This case makes for a perfect home entertainment PC to hook up to your TV, or as a small work computer that won't take up much desk space. Just be wary of putting in a high end graphics card due to size and the risk of overheating.
The current trend in PC case design is to model their aesthetics after spaceships and amusement park rides, with bright flashing lights and spinning fans. So it's nice to see some of the cleaner and more minimal designs proving popular.
While only ATX compatible, it's still the most commonly used motherboard type by far, so that shouldn't prove too much of a problem. The only reason this case isn't a little higher on our list is because it's not made by a named brand, but it's a big hit among reviewers!
This is the first of two Thermaltake cases on our list, with this being the older sibling of the pair. Its slightly larger size makes the V21 better suited to more resource-intensive builds. Although, you'll need to invest in additional cooling as only one fan is included.
If you're looking to push your small build to the limit, then this is the case for you! But if you're just after a basic PC that can squeeze into smaller spaces, then the V1 is a better choice.
Cooler Master are one of the best brands in the world when it comes to computer components, and their PC cases are some of the best quality around. If you opt for this case, you won't be disappointed!
The reason why this fantastic case sits so low is based on how much the pretty, front facing ARGB fans can set you back in terms of price. If you're happy to pay the difference, you'll still be getting an incredible case, just at a premium.
This case is available in a variety of colours, and features one of the most comprehensive selection and number of ports, including a rather useful card reader. It's also the cheapest option on our list, which is something to consider if you're working on an extremely tight budget.
Sometimes you'll find a budget case that has a premium quality to it, but unfortunately, this is not one of those. This is a cheap budget case that feels like a cheap budget case, so it may be worth investing a little extra if you're able to.
There's a lot to like about this offering from Corsair. It has a high airflow layout, three RGB programable front fans and three removable dust filters on the top, bottom, and front. A fully transparent window allows you to showcase all your components and RGB lighting.
We're well aware that aesthetics are an incredibly subjective thing, but the Corsair iCUE is considered one of the least visually appealing cases on the market today. It also sits at the more expensive end of the budget PC cases featured on our list.
In general, a case that supports a large ATX motherboard will also support Micro ATX and Mini ITX motherboards, however this is not always the case. Before purchasing, double-check the case's specifications to ensure that your motherboard is compatible.
Yes. Selecting a case with fans and ventilation allows for better temperature regulation to keep your rig functioning smoothly even during hotter months.
