It's worth asking the vendors in question if you can test the configurations
before you buy. Of course with 'generic vendor' it's easiest if that
vendor has local offices.
If Dell hesitates, mention that their competitors offer such programs;
some by loaning you the servers[1], others by having performance testing
centers where you can (for a fee?) come in and benchmark your applications[2].
