Pro-tip from an ex-university sysadmin: beware getting consumer-grade machines, and never, ever, get them if you are buying in bulk. The specs will probably all be similar, but the individual parts will be whatever was in the bin when the chassis came down the line, which means whatever was cheapest that day. Even if you get lucky and have drivers for everything, supporting 10 machines with 10 different configurations is 10 times harder than supporting hundreds of machines with one configuration.
