3x Macmini6,2 about to arrive on my doorstep. Expect to utilise as a stack as I venture into VMware ESXi territory. Base, they're 2.3GHz with 4GB RAM and 2x 1.0TB 5400RPM drives. Will be upgrading each with 16GB RAM, and thinking 2x 256/480/512GB SSD each. Can anyone tell me - or point me to an existing list - of caveats when upgrading, and known working parts? Word is Crucial memory and SSDs are actually tested in-house for compatibility Can't decide myself if the OWC products are a rort or the safest bet Think other 2012 users around the traps have been using Samsung PRO and EVO drives without any issues Recommendations on parts?
