Next, choose the storage you want to use. HDD drives are the traditional hard drives that most computers have, and they are extremely affordable.
I prefer a hybrid option that includes both. A computer built with its system files on a smaller SSD will boot faster, while a larger and cheaper HDD in the 2-TB range gives plenty of storage.
Decide how much RAM you need. If you plan on running a 32-bit OS, then you only need 3 GB of memory since the OS won’t support any more. Most likely, though, you will be using a 64-bit architecture where 4 GB is the minimum.
RAM is a relatively cheap upgrade for the performance you get in return. Choose 8, 12, or 16 GB for a better user experience.
You can also put in a DVD/CD drive, though it is not necessary, thanks to portable storage and cloud-based software.
Video and Audio Cards
If you intend to play video games, create digital graphics or edit video, you should invest in something more advanced than a basic video card.
For enhanced graphics, AMD, ATI or Nvidia cards will do the trick. The AMD Radeon RX 460 is a reasonably affordable option that can also handle the needs of most casual gamers.
The same goes for your audio card: If you are editing audio files, you should always opt for a higher-quality card that’s compatible with the peripheral equipment you want to connect.
Case, Power and Cooling
You have to buy a case to hold all of that amazing hardware! There are many types of cases on the market with different features. Many cases have a rudimentary power supply and cooling fans. However, if you are building a high-performance system, they are probably inadequate.
All that performance generates heat. Too much heat will cause your computer to crash and may even damage hardware, so be sure to invest in some qualitycomputer cooling fans
At a minimum, you will want one attached to your CPU heatsink, one larger fan to exhaust heat from the case — and if not built in, one to disperse heat from your graphics card.
The more powerful your components, the more power you’ll need to run your system properly. You don’t want to burn through a cheap power supply and have everything shut down on you.
Plan on at least a 500w power supply, but if you’ve opted for a bigger processor, graphics card, and the requisite fans, you’ll need something with more juice. Your components may come with recommended power allowances. If not, I suggest at least a 750w power supply.
Final Thought: Don’t be afraid to invest more money up front, as your custom machine can provide years of use before you’ll need to upgrade it again. Good luck with your project — and most of all, have fun!
