  • Graphics Card? - ATI Radeon X1600. Your system uses a built-in GPU so there is no options here.
  • DDR2 to SDRAM? - This is not possible. Your system has 200-pin PC2-5300 (667MHz) DDR2 SO-DIMM
  • HD RPM? - Replacing the HDD to a higher RPM drive will get you that. But you more likely want to get a SSHD drive like a 1 TB SSD Hybrid 3.5" Hard Drive
  • Interface? - The systems SATA port can’t be upgraded. Your system is limited to 1.5 Gb/s
  • Modem? - No built-in modem. Are you asking about the Ethernet port which offers 10/100/1000BASE-T connection
  • Firewire? - Not upgradable only offers 400 Mb/s
  • Processor? - Limited to Core 2 Duo CPU’s used by Apple
  • Cache Memory - L2 is part of the processor
