Ive got an internal CD drive on my A1200D and i have to admit its so useful having one!
And its so easy and cheap to do the hack aswell i just picked up a compaq laptop cd drive off ebay (less than £5) and hacked a hole in the side of my case and it all fits togather nice and snug!
Im also using one of those buffered ide adaptor/ interface things from amigakit and i supose u also need a copy of ide fix.
The HDD in mine is the normal 2.5" but because the cd drive is in there the was no way for me to mount it on to anything really so its pretty much loose inside and just rapped in anti static bubble wrap to stop it banging about and stop it from coming in contact with the mother board ..
mines a pretty sh*t hack but it does the job .. ive also got gaffa tape holding the cd drive in but u might want to do things a bit more pro than me
:crazy:
