Computer Hardware Purchasing Recommendations (7.20.11)
This list represents the Nebraska Library Commission's recommendations for libraries
planning to purchase general-purpose
computer hardware or software
It is not
intended to cover all applications or all situations.
Specialized applications such as automated library systems, desktop publishing,
gaming, or network servers may require significantly different configurations. We
also recommend viewing two of the NCompass Live sessions on the topics of computers:
What to Know Before You Buy
Setting Up Your Public Access Computers
♦ Desktop Computers or Workstations
Processor: i5 meets or exceeds typical library applications.
The icore CPUs use less power, generate less heat, and have better built in graphics than older processors. icore
CPUs have two physical cores, plus
two additional logical cores making them better at multi-tasking. Their
versatility versus cost is better than either the i3 or i7.
The motherboards that accommodate the icore processors are supposed to allow an easy upgrade path to a better
CPU down the road.
How to select a processor
Compare Intel Core processors
Operating System Software: For workstations, the Library Commission recommends Microsoft Windows 7 Professional or Ultimate edition. We recommend 64-bit Windows provided any workstations to be upgraded and any essential peripherals (printers, scanners, etc.) are 64-bit compatible.
Memory (RAM): 2GB minimum, 4GB if feasible
[more is better, but 32-bit workstations can only fully utilize approximately 3.5GB]
Hard Drive: 120GB or larger.
Monitor: 17 inch or larger LCD.
Video: If the workstation will be used for gaming, be sure the video card provides sufficient speed and memory.
Sound: Be sure to include speakers and/or headphones as appropriate.
Optical Drive: DVD-RW
DVD - Specifications, Terminology, History, etc. (from Wikipedia)
Media Reader/Writer: Provides access to
memory cards from cameras and other portable devices.
Keyboard and Mouse: Keyboard and mouse may use either PS/2 or USB ports. If you are planning on re-using an existing keyboard or mouse, be sure your new computer includes the necessary ports or adapters. Note: the same caution applies to barcode readers, trackballs, and other input devices.
Network Card: Gigabit Ethernet card.
laser printer [Higher resolutions are better: 600 dots per inch is better than 300 dpi, for example. Higher pages per minute ratings are better: 8 ppm is better than 4 ppm, for example.] A 24-pin dot matrix print may be required for continuous feed forms.
♦ Notebook or Laptop Computers
Special Considerations: weight, screen size, battery life, and/or keyboard touch & size.
Also a bag to carry it in and its accessories.
Wireless LAN Options: 802.11b/g or 802.11b/g/n integrated wireless network card.
For more information, and search for 802.11.
Fixed Optical Drives: Laptops generally come with at least DVD/CD-RW
drives at a minimum; extremely light-weight laptops may not include an optical drive.
Support/Warranty: Purchasing a technical support agreement is up to the user depending on cost and how much the user feels they will need help. Warranties are recommended as these mobile workstations tend to take some abuse during travel. If you are especially hard on such equipment, check out your options for "no-fault" warranties that will repair or replace your laptop no matter how your laptop was damaged.

♦ Additional Considerations
The links below provide checklists that should be useful once you have your new system up and running. It's also a good idea to apply them to any existing computer systems.
