I'd suggest using DIY Micro: http://www.diymicro.com/contact.asp I just put one in my G4 450 dual Gig Ethernet from them... $124 with quick, free shipping and a good return policy. The only issue I have had so far was having to upgrade to 10.2.8 to get native support, although an earlier poster says you need Toast to burn DVD+ and DVD RW. I haven't tried burning a DVD yet so more may be revealed. I used the CD drive swap guide from the XLR8 your mac site. but I think you could just add this drive to the 800 as you have 2-5" bays which the 450 lacks, assuming your not using both. IIRC, the jumpers on the boot drive/default burner must be set to the master position which is clearly labeled on the 106.
