Ventilation is a key aspect of any personal computer case and even more so for a gaming PC. Good ventilation ensures that all of your components are running at optimum efficiency as they’re cooled by whatever cooling system you prefer. Fans are the most common form of cooling and do their job well in combination with on-component heatsinks. To avoid bad ventilation, upgrade older devices like drives that utilize ribbon cables and instead move on to SATA. This is not only more efficient in terms of space, but also provides faster data speeds. For a gaming PC, you should really have a front fan pulling cold air in and a rear fan pulling hot air out. This is a good system and can be upgrade to have more front or rear fans as necessary. Additionally, there should really be space for a high-quality central-processing unit (CPU) fan. These are sometimes very large devices.
The Power Supply Unit
When purchasing a case, they almost always come with a power supply unit (PSU). If they don’t, this can be a benefit, as the supplies are often not on par for gaming rigs. All of your internal components require power and this all adds up when you’re using multiple optical and hard drives as well as one or more high-end graphics cards and high-end CPU. The power supply should be at least 700w for a gaming rig, more for machines with additional graphics cards, as each unit can require over a hundred watts.
ATX cases are the most common size as they’re small, but generally large enough for everything you need. However, it’s easily possible with several hard drives and optical disk drives that space becomes an issue. With all of the cables stretching across the space and usually a large graphics card in the middle, you may need additional room for these devices. While ATX cases do conform to generic standards, there are slightly different designs. You should look for one that adheres to your requirements, such as whether you have more of one type of drive than the other.
If you’re looking for a much larger case, consider a mid-tower case. These can boast more or larger fans, a lot more space for cables, drives and multiple graphics cards. It’s a must for those who want a true gaming PC.
