I want to use the computer for photographs and image manipulation.

Two things are required when image manipulation becomes part of your computer requirements. First, a PIII processor (750Mhz) is where you should start looking. Also, since images are huge files, a robust hard drive is required. 10gb and up is recommended. 20-30 is more desirable. Another alternative to manage the storage of image files is to use a CD-RW to burn the images to CD's as opposed to the hard drive. This will keep a minimal size hard drive (10gb) from choking on space eating images.
