The Title says it All. It does not come with a Hard Drive or a optical drive. The optical drive i don't need as i can use FireWire Target Disc Mode to install OS X Leopard. I do have a 20GB HD in my 12in PowerBook G4 that will work in the 15in PowerBook for now but i want to look for something bigger and may be even a SSD being this will be my main Laptop after i sell My MacBook. What i am going at is what SSD/HDD do you think is best? How much faster will a SSD Be then a HDD in a PowerBook with only ATA-100? I would be looking at HDD's With 120-320GB storage or SSD's with 80-120GB Storage Thanks for your help Here is the Link to the PowerBook i Bought http://www.ebay.com/itm/330714890444?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1497.l2649
