2GB DDR2 Non-ECC SDRAM,800MHz, (2 DIMM)Means 2 Gigabytes of temporary storage DDR2 – Double Data Rate Non-ECC = It is not Error checking and
correcting – ECC RAM memory is used for servers and costs more.
SDRAM - Synchronous Dynamic Random Access Memory
800Mhz – The speed data is transferred to the CPU (Faster = Better)
2 DIMM – The memory comes as two 1 GB sticks of memory

Current average size is 200GB drive
If you are storing many photos or video, buy more storage (500GB or more)
You may want to add another drive for on-line backup.
Organizing your files is key to finding your files.

For business applications, the onboard video may work fine.
If using MS Vista and you want the full User Interface experience – get a video card with at least 256MB RAM.
DVI – needed for best viewing using a flat panel display
Dual monitor support if you plan on using more than one monitor,
