I've actually been thinking about modding my PB 2300c after installing some more RAM and a new display cable. One of the first orders of business would be to up the HD to something bigger (hoping for 2.5" SCSI because that leaves the IDE bus free for 2 devices), and I really want to add an external CD-ROM drive (a round IDE cable should make that easily possible. Final thing would be an IDE CF reader. Although a little inflexible (ie, turn off power before you insert card), it would be one of the best ideas I've ever had if it works.
