1 Most desktop computers do not include a monitor. 2  See: How Much Does a Computer Monitor Cost. 3  While most desktops include at least a basic mouse and keyboard, some users prefer to upgrade. 4  A wireless keyboard costs from about $20 to over $200, a wireless mouse from about $20 to $100 or more. For those home office and general-purpose users with limited space, small form or all-in-one desktop computers cost from $1,100 to $2,100. 2  An all-in-one desktop unit hides the processor, memory and hard drive either in the base or behind the integrated flat-screen monitor.
âLet me tell you about a computer advertisement from 1993. One company was advertising 9,600-baud modems for as low as $500. Dell was selling a top-of-the-line 486 with a 66MHz processor, eight megabytes of RAM and a 320-megabyte hard drive for $4,400. The single biggest difference is in the hard drive prices. Three hundred dollars got you 80 megabytes, and a one-gigabyte drive from IBM cost more than $3,000. Single speed CD-ROMs sold for $600. Today, if you could buy this hardware, it would cost between 10 and 25% of what it cost two years ago.
