Personally, if I was going to build 30 systems, I would be looking to Dell or IBM.
If there is going to be a lot of media/video editing, you may want to opt for Intel systems as they seem to perform better at encoding. Otherwise, you should go for AMD as they seem to hold the edge in just about everything else and are usually a fair bit cheaper.
Heck, with the savings you get by going with AMD, you might be able to get a more powerful AMD system that outperforms the Intel system (that is if you want to to get the most powerful system that fits within a budget VS. getting AMD or Intel of equivellent performance and not using the entire budget)
