Advice on upgrades please!

Hi, Lee -

Re the RAM, a 512MB module won't work - the max a B&W can use is 256MB per slot. If a 512MB module is recognized ar all, it will appear as 256MB.

You will not be able to use the RAM from your iMac 333MHz machine. Among other things, that iMac uses 144pin modules; the B&W uses 168pin modules.

The hard drive appears to be an okay choice. Be sure it is ATA and not SATA.

Can't comment on the graphics card or monitor.

Almost any/all 128MB RAM is not going to run well - you could have a crash or freeze daily in OS 9, and not be usable at all in OS X due to its being 10 nanosecond rather than 8 ns. Most people would ask you to download and run DIMM First Aid to make sure that it is 8 ns. DFA saying "OK" only means that it has the correct "SPD" program code, not that it has passed any more thorough test.

Put the slowest memory first (J19) and faster memory after that (Grackle mem controller uses J19 only for Cas Latency etc).

The 9200 is fine.

7K80 - I thought that was a 2.5" laptop type.

IF you have a rev 1, ANY drive that is faster than 18MB/sec will cause data corruption and be trouble. If you have a "U bracket" in there, it supports master/slave, AND it should be fine with most any drive up to 137GB.

Of course an SATA drive would be nice and work in later systems.

Dell has great deals on monitors.
Viewsonic 20" for $350 as well.

RE: 9200 -- be sure you are looking at a PCI card not an AGP Card. This Mac has one fast PCI slot for the graphics card, but no AGP slot.
