I have come to terms with the fact that a IIFX or Quadra 840AV is not going to fall out of the sky for me. I have decided on a IIsi because I like the pizza box form factor but I do not like the limitations of the LC series. According to a post I read on here, it seems I can even cut a hole in the top to pass a SCSI cable through and attach a CDROM Drive without having to purchase an external based unit. It works with Rominator II. Are there any technical caveats or gotchas that I should watch out for specific to this machine? I already know to look for PRAM batteries that have exploded.
