Faheel - Just to complicate your life a bit more you might want to think about the following reasoning for going SCSI.
I specified a SCSI disk on the last system I purchased - sure, it cost a bit more, but my reasoning was that when I needed more disk space (and that's about as immutable as day following night!), I would relegate the original SCSI disk to a stand-alone SCSI enclosure (a two bay enclosure purchased down Tottenham Court Road for about £80)and simply slip in another (bigger) drive.
It's very useful indeed to have a large (well, 2.1Gb in this case) drive that you can connect to any system that has a SCSI interface. I also purchased (for about the same price) a SCSI PCMCIA card, so I can really put my Toshiba Libretto 50-CT (with its piddling 850Mb drive)on steroids when I need to.
Just a thought to complicate your decision process!
