I love using old computer equipment and breathing new life into it. That is exactly what Giovanni Militano did when he took some electrical parts and stuffed them into an old CD-ROM case. The resulting DIY Headphone Amp looks great! "This headphone amplifier will reside primarily on my desk at work, so it needs to fit into an office environment. Fortunately I had a dead Plextor external CD-ROM kicking around that would make for the perfect enclosure and blend in well on my desk. Even better yet, it already had a power switch, power adapter receptacle and RCA inputs on the back as well as a headphone jack on the front. Perfect!"
