as far as accounting, any base model dell should work, but I like the new Vostro machines by dell as far as business performance, I Have noticed a better quality off them.
I prefer HP for business machines w/ Athlon 64 processors, but it is a choice of the IT staff
Either way you really cant lose with bits of common sense.
If storing files on servers, Local HD size isnt very important. Fast netwok is essential, more ram is better and insures fast running.
Sad sometimes the performance you lose when using AD, School machines we used were dells w/ Pentium 4 3.4GHz/1gb ram/80gb HD and they ran like Pentium 3's with 256 ram.
So keep that stuff in mind when ordering said machines.
