G.Skill 4GB DDR3-1600 Pi Series Dual Channel Memory Kit
 

The G.Skill DDR3-1600 Pi Series memory modules have a rather funky looking heatspreader, which upon closer inspection impressed me from a design and engineering perspective. Each module is protected by an aluminum heatspreader with what looks like the spiral binding from a notebook on top. These loops are similar to what many other manufacturers implement, except they have a bit of three dimensional appeal to them.
