Pre-built vs Custom PCs: Which is Better?

The decision between a pre-built PC and a custom-built PC is a pivotal choice for any tech enthusiast. At Mwave we offer both pre-built and custom PC options, catering to a diverse range of needs and preferences. This blog will guide you through the key considerations to help you make an informed decision that aligns with your gaming ambitions and technical requirements.

Pre-built PCs: Convenience and Reliability


  • Ease of Use: Pre-built PCs, like Mwave's KATANA SUPER Gaming PC and FORGED ULTIMATE Gaming PC, are ready to use right out of the box. This is ideal for those who prefer a straightforward setup without the need for technical knowledge in assembling a PC.
  • Tested and Guaranteed Compatibility: These systems are professionally assembled, ensuring that all components are compatible and function optimally together. This reduces the risk of hardware conflicts that can sometimes occur in custom builds.
  • Warranty and Support: Pre-built PCs at Mwave come with the advantage of a 2 year warranty for the entire system, along with customer support. This can be reassuring, especially for those who are not comfortable troubleshooting potential issues.
  • Time Saved: For many, the time saved in not having to select individual components and build the PC themselves is significant. Building a PC from scratch with limited experience can be a time-consuming exercise, especially if mistakes are made.


  • Limited Customisation: Pre-built PCs offer less flexibility in hardware and aesthetic choices, with pre-selected components and software, limiting personalisation in both performance and design. 
  • Can Be Expensive: These systems often come with a premium price, especially for advanced specifications, due to the convenience of assembly and less price flexibility compared to custom builds. That being said, sometimes pre-built PCs can be more cost-effective — it all depends on the comparative price of the individual components of a custom PC.
  • Upgradability Issues: Future upgrades can be challenging due to compatibility constraints with existing hardware, potential warranty voidance, and physical limitations of the PC's design for accommodating new or larger components.

Custom PCs: Tailored to Your Specs


  • Personalisation and Flexibility: Mwave’s custom PC options allow you to handpick components based on your specific requirements. Whether you need a high-end GPU for gaming, a powerful CPU for content creation, or extra RAM for computational tasks, you have the freedom to build a PC that matches your exact needs.
  • Performance Optimisation: By selecting your own components, you can optimise the performance of your PC for specific tasks. For example, gamers might prioritise a high-end graphics card, while content creators might focus more on a powerful processor and ample storage. You have the ability to select components that offer the best performance for your budget. With options like Intel Core i9 13900K CPU and Gigabyte GeForce RTX 3060 Graphics Card, you can build a powerhouse tailored to your gaming style and future-proof your system for upcoming software and games.
  • Upgradability: Custom PCs are generally easier to upgrade. If you're familiar with each component, you can replace or upgrade parts as needed, which can be more cost-effective in the long run.
  • Learning Experience: Building your own PC can be a rewarding learning experience. It offers an opportunity to understand the workings of your computer and can be beneficial for those who wish to delve deeper into computer technology.


  • Time Investment: The process of building a custom PC requires a significant time commitment, from researching and purchasing components to the actual assembly and setup, which can be lengthy and technically demanding.
  • Warranty Complexity: Each component in a custom build typically comes with its own warranty, leading to a complex situation if repairs are needed. Managing multiple warranties from different manufacturers can be time-consuming and may require dealing with various customer service departments.
  • Compatibility Risks: There's a potential risk of parts being incompatible with each other, such as CPU and motherboard socket mismatches or RAM and motherboard compatibility issues. Thorough research and understanding of component specifications are necessary to avoid these pitfalls.
  • Higher Initial Cost: Building a custom PC often incurs greater upfront expenses, as purchasing individual high-quality components can be more costly than the bulk pricing advantage that pre-built systems might offer. Additionally, the cost of tools and potential extra components like cooling systems or additional cables can add up.

Pre-built or a Custom PC?

Whether to opt for a pre-built PC or a custom PC is a decision that hinges on personal preference, technical know-how, and specific gaming or work requirements. Mwave offers stellar options in both categories, backed by quality assurance and customer support. Understanding your priorities and requirements will guide you to the right choice, ensuring you get a PC that not only meets but exceeds your expectations.
