I haven't gone cutting in to my casing yet, i'll wait for my ACA 1230 to end up here first, but it seams straightforward enough. I figured as much that the slower flavors really were enough for WHDload's but grabbed the faster one kinda on a whim, it's not going to hurt when i go to play Elite.
I have a second piece of hardware on the way, a CF adaptor, i might even hold of on splitting the Amiga open to test the ACA1230 until that one arrives.
It's not like i got any way to get WHDload's on to the system without it anyway. (I wont be pulling the harddrive out every time i want to add something, and i don't have a nic for the Amiga...)
Thank you all for the feedback.
