I've been looking at different internal HDs and enclosures for my G4 iBook (OS X 10.3.9), and found these two items: Maxtor MaXLine III 7L300R0 300GB 7200RPM IDE Ultra ATA133, 16MB cache, 5yr warranty for $177.00, at http://www.newegg.com/Product/Produ...ategory=14&propertycodevalue=359:7788&bop=and and the Rosewill RX30-U2FA 3.5" USB/Firewire External Enclosure, IDE, for $64.99 at http://www.newegg.com/Product/Product.asp?Item=N82E16817173003 Question: I'd like to be able to connect the HD (internal + enclosure) to both iBook and PowerMac 7300/500 (G3 upgrade). Would this be a problem? What about the size limit on the PM7300/500? I have slow USB on the PM7300, no Firewire. Running System 9.1/8.6 on the PM, 200MB RAM. Any suggestions appreciated. Thanks.
