Understanding Form Factors

Desktop computers come in many shapes and sizes (form factors). Some form factors you’re most likely already aware of, but if you haven’t worked in an office or corporate environment before, then some of these may be new to you.

  • Small Form Factor (SFF): More compact design than a traditional tower computer, while still using standard size components (such as CPU & RAM). Commonly found in schools and office spaces. 
  • Micro/Mini: The smallest type of computer form factor, these are designed to fit into small spaces or mounted on the back of LCD monitors. They’re great for those needing a space-saving computer that has most of the power of a full sized desktop PC. They use the same type of RAM found within laptops (SODIMM), and usually have a power-saving orientated CPU installed. 
  • Tower: Classic design that most will be familiar with, these computers offer great upgradability and use standard sized components. For those who need a powerful workstation, a tower computer is likely your best choice.
  • All-In-One (AIO): These desktops have an integrated LCD monitor, which make them a great solution for space-saving applications. Usually offering similar performance to a Micro/Tiny PC (due to their hardware type). An Apple iMac is also considered an AIO computer, due to the integrated LCD screen. 

Key Features To Consider

When searching for the perfect desktop computer for your setup, there are a few key hardware features to consider. In our Computer Components Guide, we break down the technical side of what each piece of hardware is. We’ll briefly go-through these below to help guide you through. 

1. Processor (CPU) - When considering a processor for your desktop, especially from Intel’s range, there are a few factors that should be taken into consideration.

  • Generations: Newer processor generations generally offer improved performance and efficiency. With Windows 10’s support ending in 2025, we recommend looking for a desktop with an 8th generation Intel processor (or newer) to help future-proof your purchase. In Intel’s naming scheme, the first number of the CPU model indicates it’s generation ie. Intel Core i5 8500 is an 8th gen processor. 
  • Core Count: Intel Core i3 usually have 2-4 cores, Intel Core i5 have 4-6 cores, and Intel Core i7 or higher can have 8 cores (or more). In simple terms, the more cores a processor has, the better multitasking will be. 
  • Clock Speed: Measured in GHz, a higher clock speed could mean faster processing, however this number is commonly mistaken for ‘higher number means more performance’. 

Example: Imagine an older CPU with a clock speed of 4.0 GHz and a newer CPU with a clock speed of 3.2 GHz. Even though the older CPU has a higher clock speed, the newer CPU will likely outperform it for several reasons. 

  • Hyperthreading: Usually found in higher end Core i7 processors, hyperthreading allows a single core to handle two threads simultaneously. This improves multitasking tasks.
  • Branding Series: ‘K’ series = unlocked processor (can be overclocked). ‘T’ series = power-optimised. ‘U’ series = Ultra-low power. ‘X’ series = high-end processors for gaming and content creation. 

2. Memory (RAM) - RAM is the computer’s temporary storage space for active applications and their data.

Essentially, having more RAM allows for smoother multitasking and enhances system performance. While Microsoft Windows recommends a minimum of 4GB of RAM to operate, we recommend 8GB of RAM or above.

3. Storage (HDD or SSD) - This relates to the amount of storage space that is inside your computer.

Popular cloud storage solutions, such as OneDrive and Google Drive, have solved the need for most users to require a large amount of local storage. We recommend a minimum of 256GB storage space, and highly recommend that you ensure your device has a Solid State Drive (SSD) as its main hard drive. The newer SSD’s offer much greater reliability and performance compared to their older counterparts, the Hard Disk Drive (HDD).
