i will be running rosetta, amber, gromacs, autodock and such programs used in engineering proteins. I would also like to run QM simulations for small molecules. I need to setup a workstation cluster for the lab but dont have that much knowledge of hardware. what would be a good system and the spec for what I want to do? I was thinking of precision tower 7000 series is this a good choice? what spec should the processors have? please give me any detailed advice which a nonprofessional would understand. thank you.
