Mac mini (Early 2009)

Launched in March 2009, the Early 2009 Mac mini brought the unibody aluminum design philosophy that had just redefined the MacBook Pro down into Apple's smallest desktop, machining the mini's compact enclosure from a single block of aluminum for the first time and giving Apple's budget Mac a noticeably more premium, cohesive look than the white polycarbonate top and silver base design it had used since 2005. Powered by a 2.0GHz Intel Core 2 Duo processor, the headline upgrade was actually graphics rather than CPU: Apple swapped the long-serving, aging Intel GMA integrated graphics for NVIDIA's GeForce 9400M chipset, the same graphics silicon used in the unibody MacBook and MacBook Pro released a few months earlier, delivering a genuinely dramatic leap in graphics performance for a machine that had been graphically anemic for years. This made the mini meaningfully more capable for HD video playback, light gaming, and graphics-accelerated interface effects, addressing one of the line's longest-standing weaknesses. It also added a Mini DisplayPort output alongside DVI, foreshadowing Apple's broader port strategy shift, and, notably, dropped the FireWire port that previous minis had included, a change some longtime users grumbled about since FireWire was still common among external drives and audio interfaces of the era. Pricing remained anchored at the low end of the Mac lineup, continuing its role as the cheapest possible entry into Mac OS X for switchers and the preferred choice of home-theater PC hobbyists, a community that embraced the small footprint and, with this generation's much-improved graphics, finally got smooth HD video decoding worth building a media center around. Reviewers were pleasantly surprised by how much of a difference the GeForce 9400M made to the overall experience despite a fairly modest CPU bump, treating this generation as a meaningful, if quiet, step up rather than a mere cosmetic refresh. It set the aluminum unibody design template the Mac mini would carry, essentially unchanged externally, for years afterward, right up until the far more dramatic 2010 redesign that shrank the enclosure further still.
