Barebones Kits: Barebone computer kits or Starter Systems are a combination of the basic computer components that are required to build a system or upgrade your PC. A cheap barebones computer kit is a great way to get the base parts without the hassle of having to pick them yourself and check for compatibility issues. Going with a barebone gives you complete control over your other core components - such as memory size, hard drive, DVD drives, etc. - and lets you find the right combination to fit your budget.
