I'm planning on running the 4000Di with a Voodoo card, Sound Blaster, PCI NIC, and my A4091 SCSI. This is all of the slots filled. It looks like there is room up front to run a 60mm fan to cool the card slots. Also, I'll be swapping the standard PS for an 250W AT/ATX model. I just need to figure out what to do with the power switch. I'd like to have it look as original as possible from the outside.
