It should be just fine. My current GS computer is a K6-2 450 w/128MB ram and two SCSI drives. For IDE drives there is a special setting for DMA that you need to turn on. Go to the tips forum and read the article: http://www.northernsounds.com/ubb/NonCGI/Forum17/HTML/000003.html
and read the part about setting up an IDE drive and also the \"UPDATE\" part for setting up a PC in a non-dedicated configuration.
