I am going to get a mac mini (i7 2.6Ghz with the factory 1GB HDD) and will get an extra SSD drive (256GB) at Crucial or somehere else. I would like your opinion about if it is best to: A: get a flex cable and install the SSD and keep the HDD inside B: get an external USB3 case and place the HDD in that case. My doubts: Option A is the most tidy, but I fear damaging the Mini, and also costs more than option B; and the Mini could be hotter with both drives inside? Option B is cheaper, and I would put the HDD in the USB3 case, but the cases I'm after use the USB power, and I don't know if it will be noisy (because the HDD is outside) and if it performs well with USB3 vs inside? Your thoughts?
