What's in your arsenal?

So I decided to take the leap and start my own business on the side, out of my apartment. It's a simple PC design business, get the facts, build the machines, get a little extra dough on the side. After a long time of deciding a name I came up with 'Arsenal'. For many people, computers are necessary part of their lives and you have to have something in your computing arsenal to conquer those daily tasks. So I will be designing and building custom PC's. I will also offer up my services to anyone in need of an upgrade or repair.

A few notes on my own machine: I came in to possession of some a 2 GB stick of PC6400 RAM. The RAM was given to me by a fellow computer guru who removed it from another PC. After dropping in the stick, I heard a variety of beeps in sequence. Basically my computer was saying "What the fuck is this new crap you are putting in me!" Well, after some thought, I figure perhaps since my current RAM is timed at 5-5-5-15 and my new RAM is timed at 6-6-6-12, maybe I should switch my computer to automatically choose the right timing, as opposed to trying to run the new RAM at the old timing, woops! If everything goes correctly, she should run 4GB's at 6-6-6-15.
