Externally you can via PCI or PCIe - retrofit card, internally it is more difficult. And if you have already used the available slots, then go sometime nothing. Or perhaps thanks to the NZXT IU01.
This offers namely internally exactly been a thousand companies which are available for external devices: a USB HUB. Why for 6x front USB 6x internally tap USB? If you have only one free external USB socket, so nothing is easier than to connect a USB hub to use the connector for multiple devices. Internally, this can now also thanks to this small distributor.
The package is complete, all necessary cables and a multilingual installation instructions are included. The Hub is connected via an internal USB 2.0 connector (equivalent to two external USB 2.0 jacks). To ensure the power supply is a free plug for the connection of CD / DVD drives is also the power supply required, namely the old version, as it was customary for PATA drives. Then you can place the HUB in any case by self-adhesive strips. Even the later detachment is no problem, because a kind of Velcro is used. Now stand in lieu of lost socket (= 2x USB 2.0) Three new internal (= 6x USB 2.0) and two external connectors (soldered directly on the board) available. These can share the bandwidth of the two original USB 2.0 ports. Thanks to the extra power and the connection of 2.5 inch USB 2.0 - hard drives without any problems. Logically you need for a USB hub no driver, from Windwos98 up the operation without any problems.
Sure there will be not many who use such a product. Therefore, a price around 20 Euro is very fair, especially since I was not aware of any competing product. The build quality is decent, only one connector from the power adapter cable was elaborated a little dirty with me, which was no problem. All in all, I give it 5 stars and thus an absolute buy recommendation.
