I’m taking some time to slowly upgrade the system recommendations. So far, I’ve done the “super economy” (<$500) system... I'll work my way through the remaining systems and do the server/laptop versions as well.
The system recommendations are a sort of list of components and approximate net prices of systems that I (and others) think are good. They represent the most common senses, best price for best technology systems that are available part by part. Many of people are finding ways to either build these things from scratch or, they have had their boxes so long that there isn't s single part left that is OEM. So, keep your eyes peeled for more.
