Computers with small cases, sometimes referred to as small-form-factor (SFF) systems, provide the advantages of a full-sized computer in a space-saving design. While compact, these low-profile systems may lead to additional expense and problems down the road as user requirements change.

Expansion Limitations

Video of the Day

By their design, SFF systems offer small businesses a good, basic computer setup. They basically have everything a full-sized tower offers, just in a smaller size. The main difference is in terms of future expansion. Full-sized tower systems usually have plenty of space available for the addition of another hard drive, RAM or video card, whereas a SFF system utilizes every inch of space. This leaves no room for growth or expansion. This may mean the entire system will need replaced when the limit of the current configuration has been reached instead of the lower cost option of purchasing additional components to expand.

Hot and Noisy

Computer components generate heat during operation, and this heat can cause damage to the machine if not properly vented. Unlike their tall-tower counterparts, SFF systems essentially cram all the components together for the sake of a smaller profile. While good for desk space, this small design can actually contribute to overheating. As the temperature rises inside the case, the computer may exhibit warning signs such as freezing and random shutdowns. If the system fans have to work hard to cool the components, the SFF computer can be noisy too. Most well-built (and typically more expensive) SFF systems, however, use low-power components, reducing heat and noise issues.

Limited Power

If your computer needs are limited to relatively simple tasks that don't overtax the processor, such as word processing or Web browsing, an SFF system might meet your needs. But if you need a faster, more powerful system for graphic design, video production, CAD, or other processor-intensive work, even an SFF with the most powerful configuration may not be able to handle it. Systems vary, though, so when shopping, compare the CPU, memory, graphics processing, and other capabilities among SFF and full-size systems to make sure you get the system that meets your computing demands.

Price and Upgrade Considerations

In some cases, these little computers pack a big price tag. Some SFF systems cost as much as, or more than, a full-sized desktop system. Although SFFs may save desk space, the ability to upgrade and add more memory or hard drive space as necessary without much trouble may make a full-sized tower a better choice. Desktop computer components are all interchangeable, and generally affordable, for the most part, as opposed to the pricier, smaller-sized parts necessary for SFF systems. Some SFF systems also require proprietary parts, meaning only the components produced by the company that manufactured your SFF will work with your system. This may mean a higher price tag on upgrade parts, such as RAM or a new video card.
