To install the operating system you will need a CD with ``ISO image'' ubuntu-7.10-desktop-amd64.iso (MD5 checksum 61c87943a92bc7bf519da4e2555d6e86). You can order this CD from Ubuntu for free; or you can create the CD using a computer that has an Internet connection (to download the ISO image), a CD burner, and a blank CD.
To configure and use the standard workstation you will need a keyboard, a touchpad/trackball/mouse, a monitor, and an Ethernet cable attached to the Internet. Collect this equipment for later use.
If you have only one keyboard, mouse, and monitor, and you need those to operate an older computer, you have two options:

Variant: dual-core CPU. The Core 2 Quad has four processing cores, like a 4-CPU computer. Switching to a two-core computer means spending less money on the CPU (currently $233 instead of $279). Of course, this also reduces the computer's speed for parallelizable operations.
Variant: less memory. The standard workstation has 8GB of RAM; you can save $180 by reducing 8GB to 2GB.
Non-recommended variant: non-ECC memory. Make sure to buy ECC DIMMs. I have a separate page discussing the importance of ECC memory.
Variant: more disk space. If you have more money to spend, the hard drive is one of the most obvious places to spend it. For example, you can buy several drives, and store data with parity using software RAID level 5. (Parity is an easy-to-use automatic backup mechanism: your latest data is still accessible even if a drive dies. Three disks with parity can store as much data as two disks without parity.) Make sure you have enough connectors, cables, and space for your drives.
Non-recommended variant: tape drive. Extra disks are a much better choice than tapes for backups. Disks used to be substantially more expensive than tapes, but they're now less expensive per gigabyte than almost all tapes. The only exceptions (160GB Super DLT II tapes, about $0.18/gigabyte; 200GB LTO Ultrium 2 tapes, about $0.13/gigabyte) require tape drives that cost over $1000. Even if you have so much data that you don't mind the cost of a tape drive, investing in tapes is silly: tapes wear out much more quickly than disks (a heavy-duty tape is rated for, at best, writing a few million gigabytes, which is equivalent to only about two years of disk use), and the replacement cost of disks is dropping much more quickly than the replacement cost of tapes. Of course, disks are also much faster than tapes.
