I currently use PC with iwill motherboard and 166 MHz Pentium MMX. Motherboard has built in Adaptec wide SCSI board and I run two SCSI hard discs (2.1 & 1.0 GB). Board has also Enhanced IDE drive from which I run CD ROM device as a slave. I have 64 MB of RAM.
I obviously can use more (much more) HD space and here is my temptation to buy an IDE drive, which are considerably cheaper than SCSI high capacity drives. I am being told, however, that mixing these two types is not generally rewarding (installation difficulties, slower speed, etc.). I would use my existing SCSI drives to boot and run many operations while IDE would be used mainly for storage of graphics, non essential programs, etc. If you reccomend this transaction, I plan to get myself a HD between 10 to 18 GB, which in SCSI version is kind of my reach.
