Apple Mac Mini

Compact Case Is Designed for Smaller Work Areas

This compact computer is smaller than the standard and midsize tower PCs that fit under your desk, making it ideal for limited work areas. Small case designs vary, too. However, such PCs tend to be underpowered (especially on gaming), and mini cases also have few available expansion slots and drive bays. Generally you'll have to expand the system via USB, FireWire, or eSATA peripherals, so make sure your compact system has a large number (and assortment) of ports.

Compact PC Uses an Older Laptop CPU

This compact desktop uses an older Intel Core Solo or Core Duo mobile processor, originally designed for a laptop. The 32-bit Core Duo--which shouldn't be confused with Intel's current 64-bit Core 2 series--offers only middling performance by today's standards, running roughly as fast as AMD's Turion X2 processors. The cheaper Solo version of the dual-core Core Duo fares worse in multitasking performance as a result of having one of its cores disabled.

A PC With Little Included RAM Can Do Light Work

This system offers less than 1GB of memory, which is the bare minimum that any full-featured new computer should include. Whether this amount of RAM is optimal for you depends on the PC's operating system: Windows Vista and Apple's Mac OS X don't run well with less than 1GB, Windows XP is fine with 512MB and not too bad with 384MB, and Windows 98 is good with 256MB. Depending on the distribution, Linux can run with as little as 128MB, but most Linux users are better off with at least 512MB--and 1GB is better.

The more installed memory your PC has, the more applications you can run smoothly at once, and the better the system will perform. Upgrading memory in a desktop after you purchase the PC is a snap, but usually it's worthwhile to buy the amount of memory you want preinstalled with the system.

Adequate Hard-Disk Capacity for Business or Light Home Use

With respect to hard-drive space, this system is in the low-to-midrange tier. Whether that's important depends on your needs. Though video gobbles up drive space at a prodigious rate, most other data types take up far less than 500GB.

For basic business purposes or light home use, even 80GB or 120GB might be enough. A better minimum is 300GB, especially if you download movies or music. Compact desktops that use smaller, 2.5-inch laptop drives offer less capacity. In that kind of setup, 120GB is a more realistic minimum, though 80GB will be enough for most users.

Integrated Intel Graphics Chip Can Handle Everyday Computing

This system uses a video chip from the leading graphics-processor manufacturer in the world: Intel. Though nVidia and ATI enjoy all the press, Intel has the biggest graphics market share because it supplies the integrated graphics chips for a huge number of desktop computers. For everyday computing, the performance of an Intel GPU is excellent. Unfortunately, by current standards the gaming performance is pathetic--largely because these chips usually use system memory instead of faster dedicated graphics memory.

With this PC, stick to business or general-application home use. And since only the most recent Intel GPUs can drive large wide-screen displays at their full resolution, be sure to check the chip-specific specs.

Apple Mac OS X: Elegant, Stable, and Intuitive

This system is running the elegant Mac OS X operating system, the current version of which is OS X 10.5.x (Leopard). Though OS X itself can't run Windows programs, you can run Windows (or Windows applications) on the latest Intel-based Mac hardware using software utilities such as VMWare Fusion, Parallels Desktop, or Apple's own Boot Camp. Because OS X has robust Unix underpinnings and isn't required to support as wide a range of hardware as Windows is, it's extremely stable as well as visually pleasing and intuitive to the new user.

FireWire Port Allows Rapid Data Transfer

The FireWire connection (also called an IEEE1394 or i.Link port) in this computer can rapidly transfer data to and from a range of devices, most commonly video cameras, external hard drives, and advanced sound cards.

Generally desktop PCs have a full-size six-pin FireWire port on the rear, often on a front panel. Some also include the smaller, unpowered four-pin connection that you can find on laptops and certain consumer electronics devices. (Camcorder makers often bundle a six-pin-to-four-pin FireWire cable because of this.)

The newer FireWire 800 (IEEE1394c) implementation is not backward-compatible and uses a nine-pin connector. If your peripheral (such as a video camera or external hard drive) uses FireWire 800, you should double-check to confirm that every desktop PC you're considering supports it, too.
