The Phanteks NV7 is the objective winner of this comparison, securing more category wins across the evaluated specifications. Its most significant advantage over the competition is its storage capacity, offering 100% more 3.5" drive bays. This makes the Phanteks NV7 the superior choice for users who prioritize internal hardware expansion and mass storage capabilities within their system build.

Choose the Phanteks NV7 if your primary requirement is maximizing the number of 3.5" drives housed within your chassis. Conversely, select the Thermaltake The Tower 300 if your priority is a more budget-friendly option, as it holds a 20% advantage in MSRP. Both cases offer distinct benefits, so your final decision should depend on whether you value additional storage hardware or a lower initial cost for your PC build.
