Help me Build a PC

A lot of reviewers don't mention the issues with Single Rank vs. Dual Rank RAM in terms of adding more in the future.
This important info dictates what RAM to purchase now more than anything else.
Thanks for pointing this out.

While that may be true an SSD will make a notable improvement in over all performance of the build -- even in a 500 dollar build. If you can get one for the same price as a small hard drive I'd say buy the hard drive later when you can buy a big one for storage purposes.
