I'm soon to be in receipt of an i7 mac mini with base RAM/Storage. My thinking was to upgrade the RAM and install an SSD myself (I'm cheap like that). I'm ok with the RAM instalation but I'm slightly hesitant in taking the machine to bits to install the SSD. I want the SSD for boot/load speeds and I wondered if having it hooked up externally via TB or USB would negate the effect of having it in the first place? I'm sure putting it inside would get the most out of it, but are there any downsides to putting an SSD in a caddy and cabling it up? Many thanks for opinions.
