Thermaltake Core V21 Review: Get stacked
 

Bored of the same old computer case? Thermaltake want you to GET STACKED! Yes, their Core V21 can be stacked together (and the bases removed) to increase the size and capacity. It is a very unusual design, but at £48 'per case' it may make for some interesting mods.
