The Panasonic Q, a Japan-only hybrid of the Nintendo GameCube and a DVD/CD player released in December 2001, has become a sought-after collector's item due to its scarcity, with working units rarely selling for less than $1,000 today. The device was born out of Nintendo's need to compete with the PS2, which had a built-in DVD player, and was made possible by an existing partnership between Nintendo and Panasonic's then-parent company Matsushita, which had helped design the GameCube's optical disc format.

Despite its ambitious design, the Q kept its gaming and home-theatre functions almost entirely separate, requiring a manual switch and effective reboot to move between DVD playback and GameCube gaming, with game audio limited to standard analogue output rather than the console's Dolby Digital and DTS surround sound features. It launched at ¥39,800 (about $313 at the time), a high price that struggled to compete with the more established PS2, and it never released outside Japan, though modified units were imported abroad. Its low production numbers mean it now regularly commands high prices from collectors on platforms such as eBay.
