I'm using all 7 slots (2 207 MB 3 1/2" drives that came with the system, an exabyte tape drive, a 1xCDROM, a Tanberg 1/4" 150 MB tape drive, 2 elite 1.6 gigabyte 5 1/4" drives.). I'm also out of space. If I wanted to add a faster 2nd CDrom, I'd have to take something out. If I wanted to add more disk space, I'd be out of slots. If I wanted to add a scanner or DVD drive, I'd be stuck, etc. Plus, its faster. The bus is not so expensive at about $230. Jacob
