Our full customization PC listings are organized based on their physical size: with Mini (ITX) being the smallest, Compact (MATX) being the mid-size and Standard (ATX) being the largest. The size of the PC will determine the type of motherboard and case to be used.
Space Constraint: If you only have a very tight space to put your PC, you will have to consider our Mini (ITX) build. Its general dimension is (L)38cm x (W)21cm x (H)35cm.
Graphics Card: Most of the ITX cases will not be able to fit the higher-end graphics card (RTX 3080 & RTX 3090) series with proper ventilation. Even though some cases can fit, we wouldn't recommend it as the PC might be too hot and it will throttle the performance of the computer.
Budget: The Compact (MATX) build is the most value for money as MATX motherboards and cases are cheaper in general. If you are looking to build your PC below $2k, then you should go for our Compact (MATX).
Space Constraint: The dimensions of a MATX build are roughly (L)39cm x (W)19cm x (H)40cm, suitable for small computer space. The Compact PC comes with 3 or more fans for better cooling.
Airflow: If you are looking to build a high-end rig (Ryzen 9/Intel i9 processor with RTX 3080/RTX 3090), you can consider the Standard (ATX). These high-end processors and graphics cards will generate alot of heat when on load, so the bigger case will allow better airflow to cool the system.
Graphics Card: High-end graphics card (RTX 3080 and above) will not be able to fit in the MATX build, as it is physically too big. These GPUs will also require better airflow so that the PC will not over-heat. Also, the PC looks cleaner and less cluttered when the big graphics card is installed in an ATX case.
