DIMM+SO-DIMM stackable holder

Stackable box to store huge amount of RAM modules. Can store 16 DIMM modules DDRx, SDRAM and RDRAM up to 4mm thick (desktop modules without heatsink or with thin heatsink, not like HyperX Fury for example) or 6-8 DIMM modules wtih huge heatsinks (ECC REG or gaming modules, like G-skill trident-z) or 32 default SO-DIMM modules (SD-RAM SO-DIMM can't hold well while shaking).
