The noisekiller looks pretty cool.
I installed a quiet 80mm fan (rubber mounted) in the PSU of my A2000, and also a Nexus WaveAir in the slot between the CPU card and the first Zorro slot. (The only thing left is to install some filter material in the bottom vents in the front.)
The CF card will likely be much faster than your current SCSI drive. I'm getting just under 10 MB/s (raw) on the TekMagic SCSI with an 8GB Ultra II Sandisk card.
