Yes, console is best. There are batch utilities available for mass installation of FAH , never used them myself though.
Here's what I do, download latest console version. Using a file manager make directories in target machines, then copy the download into each folder. Then I go to each machine and make a shortcut on the desktop adding any flags, then run them, they will auto config on first run. The option you suggested should also work if I'm seeing what you're thinking. Only problem is if you have a dual/quad core which need to have the machine ID's set.
If you want to monitor the systems, then the Electron Microscope would do nicely.
Well, this is still the best monitor out there but unfortunately its no longer supported so you have to update the database by hand. Also it doesn't support many of the newer cores or GPU, SMP ,etc. I use FAHSpy these days but FAHMon or HFM.Net or alternatives worth looking at.
