In today’s world, almost everything has a USB connector attached to it, and if you’re using an older computer rig, you’ll probably have a shortage of USB connectors. If that’s the case, the NZXT IU01 internal USB Expansion System might be able to come to your rescue. Costing $19.99, it enhances control and boosts power for the front-panel USB devices by connecting them directly to the power supply (as opposed to the motherboard). It also features 6 additional internal USB ports, allowing you to plug items that you don’t constantly access like a Bluetooth module or USB wireless adapter.
