Building a custom PC is no easy task, especially for beginners. Luckily, there’s plenty of help available online. If you’re looking to brainstorm ideas for your next build, here are 12 of the best custom PC building websites to help you navigate the process.

1. NZXT BLD (Best Custom)

Compared to the other best custom build sites on this list, BLD is relatively new. The brand is a subsidiary of NZXT, a well-known PC hardware and peripheral manufacturer. It also has one of the most comprehensive PC customizations that both new and veteran PC builders can quickly appreciate.

Unlike most PC builders that have pre-configured builds, BLD gives you complete freedom to build your own rig. By answering a series of step-by-step questions on the company’s website, you can create a PC that meets your personal needs and preferences. You can also choose your budget, the main games you plan to play, and other parameters to help you choose the best components for your rig. After you enter all of your filters, a few suggested builds will appear.

2. MainGear (Best choice for tech enthusiasts)

MainGear has been delivering quality builds since 2002, offering desktop, laptop, and workstation systems. Their beautiful website features a 3D customization tool that lets you see the changes to your custom PC in real time. You’ll find a variety of configurable presets, including the MG‑1 desktop starting at $1,549 and the Rush starting at $21,945, along with the Pro WS starting at $3,749.

While MainGear builds can be quite expensive, their top-notch quality and smooth performance are often worth the money. Each build comes with a 1-year parts replacement warranty (upgradable to 3 years), providing added peace of mind when servicing internationally.

3. PC Builder (Best for DIYers)

PC Builder offers both pre-built PCs and individual components (purchased through Amazon), with all-in-one systems starting at $589 and fully custom builds typically costing $800 or more. The platform is available in the UK, Australia, India, Italy, Spain, Canada, and the US, with widespread local delivery.

Additionally, the PC Builder website ranks computer components based on their performance, helping new users choose the best computer components for their system. The highlight of the website is that there are over 19,000 components available.

4. Origin PC (Best for Graphics Card)

Origin PC is one of the biggest names in the PC building market, founded in 2009 and has always provided excellent service. The company offers both custom desktops and laptops, targeting gamers, professionals, and everyone in between. Gaming is, of course, Origin’s main focus.

This PC builder has a range of options for every user, from small mITX PCs to much larger workstations, all housed inside custom-built Origin cases. This ensures that every configuration offered has been tested and the components are compatible.

Origin PC has a great Gaming Desktop Advisor tool that makes it much easier to configure the right PC for you, and the company also offers financing options, giving you the opportunity to pay for your PC over a long period of time.

One of the main benefits of Origin PC is its stock availability. Unlike many other custom PC builders, Origin has maintained a steady inventory of graphics cards over the past few years. This certainly makes up for the long wait times you’ll experience.

5. Xidax (Best warranty period)

What sets Xidax apart from its competitors is its lifetime warranty on PC components. However, there are a few exceptions, such as AMD video cards and liquid cooling components, which have shorter warranties.

Xidax will typically replace defective parts with equivalent parts free of charge. Xidax also offers a 45-day money back guarantee, subject to a 20% restocking fee.

The company also offers some of the cheapest entry-level gaming PCs around, and is also known for its quality custom PC builds that focus on matching components that work well together. Xidax’s online catalog is also well laid out, from the least powerful X-2 to the powerful X-10 models.

6. Digital Storm (Best for International Clients)

If you’re outside the US, consider Digital Storm’s line of PCs. One of the few custom PC companies that ships internationally, the company was founded in 2002 and sells custom workstations, laptops, and desktops for professional and gaming use.

Digital Storm also has some of the most affordable gaming PCs on this list. For example, Digital Storm's Lynx Mid Tower starts at $1,000 and comes with two dedicated GPUs.

Digital Storm is also known for implementing complex setups and creative water cooling configurations.

7. CyberPowerPC (Best for Beginners)

Known for its wide selection of components, CyberPowerPC is one of the best custom PC building sites. The site also offers financing options through Affirm.

You can also find custom-built gaming rigs for the hardcore gamer. CyberPowerPC also offers a variety of services, from professional cable management to complex water cooling solutions, along with an already extensive list of component options.

However, CyberPowerPC has a slower shipping time, which can take up to a few weeks. If you want your order shipped faster, you can sign up for Amazon Prime or pay for expedited shipping.

8. Falcon Northwest (Best for Custom Painted High-Performance PCs)

Falcon Northwest is one of the oldest custom PC builders in the industry, building custom computers and laptops since 1992. They specialize in high-end gaming desktops (the Talon series starts at $5,080) and TLX ultraportables (starting at $3,519), all of which can be configured through a streamlined builder, including CPUs, memory, premium cooling systems, and custom painted cases. Their international distribution ensures that you can order a custom desktop or laptop no matter where you are.

The build tool is attractive and easy to understand, covering a wide range of categories, from CPUs and storage to a variety of case options. Falcon Northwest only builds high-end, high-performance laptops and desktops. However, Falcon Northwest does not offer in-house financing; customers can arrange third-party financing using a credit card or PayPal Credit.

9. AVADirect (Best Automated PC Building Tool)

AVADirect has long been considered one of the best PC builders on the web. As a giant in the market, the company is able to deliver great value custom PCs with minimal effort on the part of the end user through its smart PC building system.

Simply provide your budget, the games you want to play, the size you want your machine to be, and the brands you’re comfortable with, and you’ll be presented with a long list of machines that might meet your needs. Once you’ve found the right computer for you, you can further customize it to make sure you have exactly the right setup.

10. Puget Systems (Best for Custom Workstations)

You may find Puget Systems’ website less appealing than some of the others on this list, but don’t judge a book by its cover! This is one of the best custom PC building websites, specializing in professional workstations. One great feature of Puget Systems is that it can recommend systems that are suitable for different types of work, including content creation, engineering, and scientific computing.

Each class is organized into subgroups, allowing you to find recommended systems for specific applications and tools. For example, you can ask Puget Systems to recommend a build that works best with Autodesk 3D Max.

11. Newegg Custom PC Builder (Best Recommendation for PC)

Newegg has a dedicated custom PC builder with a powerful AI recommendation engine. You can choose from entry-level (under $1,200), mainstream (under $2,000), and professional (over $2,000) PC builds to get tailored recommendations. The main tool offers powerful filters along with a compatibility checker and combo generator to save money on building an entire system.

The “Build with AI” feature is still in beta, but it’s great for finding personalized recommendations. You can chat with the tool and tell it your specific needs, and it will find the right components. For example, you can tell the tool your budget, the purpose of the build, and the specific components it needs, and it will generate a complete build that fits.

12. Velocity Micro (Best for Fine Crafting Workstations)

Velocity Micro, also known as the “refined PC brand”, is known for handcrafting each system to ensure meticulous attention to detail and impeccable build quality. From gaming rigs to powerful workstations and servers, each PC is built to exacting specifications.
