Yes, if you have a spare blank front bezel or don't mind having the Zip hole in front of a hard drive - luckily mine came without a Zip drive (I think they were optional when new) so I had the right bezels for hard drives. The 8600/9600 tower has space for even more drives, as well as 6 PCI cards though - I don't know why they made it smaller, as I think bigger is always better when it comes to tower cases!
