Wow. OK, in order to make sense of this thread you have to specify WHICH Mini and WHICH iMac you are comparing
Here is the recent Mac lineup and the RAM types for each
DDR 333 MHz PC2700 184 pin DIMMs (although PC3200 are commonly used)
- Mac Mini G4
- USB2.0 eMacs 1 GHz and up
- PowerMac G4 "Mirror Drive Door" models
DDR 333 MHz PC2700 200 pin SODIMM "laptop RAM"
- iMac G4 flat panel 1 GHz and above - user accessible socket only
- All Powerbook Aluminum models and all iBook G4's *
DDR 400 MHz PC3200 184 pin DIMMs
- PowerMac G5 prior to Oct 19 2005 Single and Dual Processor
- iMac G5 1.6, 1.8 and 2.0 "Rev A and B"
DDR2-533 MHz 240 pin DIMMs (PC2-4200)
- PowerMac G5 Dualcore and Quad
- iMac G5 "iSight" 1.9 and 2.1 GHz
DDR2-667 MHz 200 pin SODIMMs (PC2-5300) "laptop memory"
- Mac Mini intel Core Duo and Core Solo
- MacBook Pro
- iMac intel Core Duo
* there are some models listed under PC2700 which are actually specced for PC2100 -- however any reputable Mac RAM seller will provide compatible PC2700 memory for these.
Thanks
