I'm thinking of getting a stock mac pro and upgrading it to 2 GB RAM (no, I can't afford to go higher right now, sad, I know). I can get the 1GB upgrade for $275 at Apple (with an EPP discount), but I'm hearing that RAM prices are on their way down once again. Can I get it somewhere else for less than $250? Wow -- that's great! I assume there is no trick to installing the ram oneself. Right?
