Just like the first four parts of this never ending brain surgery series, this is about another memory upgrade.

1. G5's memory upgrade
2. iBook 1.2GHz memory upgrade
3. 1.67 GHz 15" PowerBook 1GB DDR-2 memory upgrade
4. 2nd Harddrive for the G5 • Seagate Barracuda 250 GB SATA drive

However, this was most likely the final voluntary "brain surgery" performed on the good old Power Mac G5 that I had bought in November 2003. It's a M9031LL/A, a 1.8GHz single Processor Mac with a 900MHz bus and 4 memory banks (each with 2 slots), which take PC3200 DDR SDRAM DIMM memory. The G5 came originally with 512 MByte RAM and was upgraded with 2 additional 512 MB Ram modules to 1.5 GB in February 2005.
