Bring back copper coolers

Launched in 2008, the Scythe Ninja Copper marked Scythe's fifth anniversary. The 1015g juggernaut was designed for active and passive cooling in mind, thanks to widely-spaced fins. More than 15 years later, the CPU cooler still works great, and looks surprisingly pristine (copper tends to oxidize and darken).
