That sounds great John. T-shirts and a keyboard. If it's anything like the Sarasota meet we practically had a computer flea market going. So there's a good chance everyone can leave with something.
As far as CPU, I'm running a Sempron which is similar to the Celeron and I also have between 3-5% when running GPS, Music, and vis.
BTW I have an AMD board and CPU I will be giving to whoever is interested. It is a MATX
which is 9.5" x 9.5"
