Prebuilt PCs can be easily rebuilt with a new case and most of the time you will not get any issues. Check out the reasons to swap the case and a general guide on how to do it.

Can you case swap a prebuilt PC?

Yes, you can absolutely swap the case of a prebuilt PC for a better one that suits your requirement. Prebuilt PCs are also made up of a traditional case and usually, they are very compact. Therefore, to improve the upgradability of the PC, you can change the PC’s case for a larger one.

Let’s go through the reasons why you need to replace the case of your prebuilt PC and the simple steps you need to do to make the change.

Reasons to swap case in a Prebuilt PC

If you look at the PCs available commercially, they will be powerful but very compact in size. The manufacturers use a perfectly fitting case to save cost. 

This small compact case will not provide you the sophistication of upgrading the PC with different hardware components. A case has the ability to last for decades. But the tech inside it will upgrade every year.

Each year you have tech companies innovating and upgrading the computing performance which at one point will force the consumers to upgrade their old tech to be in harmony with the current generation.

Therefore, the main reason for swapping the case from a commercial PC is to increase the chances of upgrading it.

The compactness doesn’t allow you to install a large graphics card, increase your PSU wattage, install an efficient cooling system or even you cannot install an extra cooling fan for the PC.

Due to such shortness in upgradability, it is very much needed to shift the hardware components from the existing prebuilt case to a much larger PC tower case.

Another reason might be of personal choice but it is also a valid one. Most prebuilt computers don’t have a cool-looking case. They are very formal and look blunt. Even if they have high-tech hardware, they are encased in a box with minimum style.

Therefore, if you have a better case with cool LED lighting, you can very well swap the dumb-looking case for the better one.
