| Mid Tower (Micro ATX) | Armaggeddon Tesseraxx Core 2 | Reasonably priced, nails the basics of providing reasonable upgrade space and sufficient airflow |
| Mini-ITX | NZXT H210i | Space-saving, portable |
| Full Tower (ATX) | Cooler Master’s Masterbox TD500 | Sufficient space for future upgrades, unmatched cooling support |
2. Motherboard
Motherboards like B460 AORUS PRO AC (available on Bizgramsg Official Store) serve as the backbone of your gaming PC build. Rather than being just a component holder, a solid motherboard optimises your hardware so you can enjoy faster Wi-Fi speeds or attempt overclocking (tinkering with internal settings to make your rig work harder)!
While most How to Build A PC guides might recommend you getting a premium motherboard with all the bells and whistles, beginners don’t need features that they won’t fully benefit from. That’s why you’re better off simply buying a basic motherboard that comes with enough slots and ports for your PC.

| Type of motherboards | Recommended | Comparison |
| ATX | B460 AORUS PRO AC | Highest capacity for installing new upgrades |
| Micro-ATX | ASUS TUF Gaming B550M-Plus | Smaller in size compared to the ATX and lowest in price |
| Mini-ITX | ASUS PRIME H310I-PLUS R2.0 | Most portable and fits into mini computer cases |
3. CPU
For most beginners, it’s surprising how a tiny chip like the Ryzen 7 3700X and i7-10700K (both available on mydigital2u) can control the entire PC. To truly measure a CPU’s performance, you can refer to benchmark tests performed online to decide which CPU best fits your needs!
When comparing AMD vs Intel CPUs, we recommend getting a mid-tier CPU so you can game comfortably without spending too much money. Conversely, if you’re intending to edit high resolution videos and images, invest in a premium CPU so you can enjoy its high rendering speeds.

| CPU | Recommended | Comparison |
| i3 / Ryzen 3 | Ryzen 3 3100 | Consumes the least power and is the most budget-friendly. However, it’s ranked the lowest in performance among most CPUs. |
| i5 / Ryzen 5 | Ryzen 5 3600 | I5 and Ryzen 5 CPUs enjoy higher performance while being slightly more expensive |
| i7 / Ryzen 7 | i7-10700K / Ryzen 7 3700X | i7 and Ryzen 7 CPUs open up more doors for multitasking thanks to hyper-threading and turbo boost |
| i9 / Ryzen 9 | i9-10900X / Ryzen 9 3900X | The best CPU available on the market. Built for intensive gaming and video editing. |
4. Memory
When building your own PC, one of your biggest concerns should be to ensure there’s enough memory for running intensive software. This can be accomplished by equipping your rig with enough Random Access Memory (RAM). For starters, you can rely on RAM sticks like Crucial DDR3 RAM (available on supergoodram.sg) and Corsair Vengeance RGB PRO DDR4 RAM (available on Corsair Official Store) to keep things running smoothly! For today’s standards, we recommend future-proofing your rig with at least 16GB.

| Types of RAM | Recommended | Comparison |
| DDR3 | Crucial DDR3 RAM | Budget-friendly option. Slowly being phased out as motherboards make the transition to DDR4 RAM. |
| DDR4 | Corsair Vengeance RGB PRO DDR4 RAM | Increased memory capacity, speed and power efficiency as compared to the DDR3. Incompatible with older motherboards. |
5. Cooling system
Cooling systems are essential to keep your rig running at optimal temperatures. Ultimately, it comes down to personal preference when choosing between the simple brushless fan or the impressive MasterLiquid ML240R (available on Cooler Master Official Store). If you are tight on funds for your gaming PC build, go for the fan since it gets the cooling job done. However, if you plan on maximising PC performance, we recommend going for the liquid cooling system as it’s more efficient, allowing you to achieve greater performance through overclocking.

| Types of Cooling Systems | Recommended | Comparison |
| Air | Brushless fans | Easier to install and is budget-friendly. Aside from dust clearing, it does not need regular maintenance. |
| Liquid | MasterLiquid ML 240R | Increased cooling efficiency and more aesthetically pleasing. Requires regular coolant change. |
6. Power supply
You might be wondering why How to Build A PC guides often claim power supply units to be the unsung heroes of any gaming PC build. Although power supplies (PSUs) like Superflower 650W Leadex III Gold (available on Bizgramsg Official Store) might lack the appeal of flashier components like graphics cards or liquid coolers, their ability to provide consistent power to the rest of the components is crucial to maintaining your PC’s long-term health.
How to build a PC — picking power supply units
Power supply units are usually differentiated by wattage and efficiency ratings. After calculating the total amount of power consumed by your PC, buy a PSU that offers 20% more wattage than what you need. This ensures your PC isn’t consuming more power than necessary and creates a safe amount of spare wattage for your PC to avoid overloads. For exact wattage,you can refer to this handy power supply calculator by CoolerMaster.
7. Storage
Storage options are incredibly varied, with different mixes of speed and capacity. If you’re craving those lightning fast boot-up times, you’ll need a modern internal Solid State Drive (SSD) like Samsung’s 860 EVO (available on Bizgramsg Official Store). Alternatively, if you require a hub to store all your data, you’ll require an old-school internal Hard Disk Drive (HDD) like Toshiba’s NAS N300 HDD (available on Toshiba Storage Official Store).
We recommend buying both so you get the best of both worlds! Simply install your operating system and software on the SSD to take advantage of its faster reading and writing speeds. As for everything else, just store them on your HDD!
