Removing four thumbscrews on the large left side panel gets you inside the tòu. There is a second smaller panel which also needs to be removed to install the power supply. For a first time installation, you'll also want to remove the two panels on the opposite side as well as the two at the rear.
For all its attention grabbing greatness on the outside there is surprisingly very little to raise your curiosity on the inside.
You get three tabs that are designed to support 3.5" or 2.5" drives along with room to mount a pair of 2.5" drives on the back panel. There is also that 5.25" drive bay at the very bottom which we used to tuck away excess cables.
You won't need a motherboard I/O shield when building in the tòu -- or at least you won't be able to use it as there isn't a mounting spot for one. In this case, not having a motherboard I/O shield isn't necessarily a bad thing as it isn't exactly required with the rear glass panel.
There are seven expansion slots for PCI/PCIe cards and room for an ATX power supply up to 220mm long.
Keeping things cool is a single front mounted 120mm intake fan which is fixed into place using a rubber strap of all things. Then at the top there are three 120mm exhaust fans and room to support a 360mm radiator for liquid cooling, because in this case you know you want to.
As limited as the interior features are, that sand-cast aluminum frame is pretty impressive and measures up to 4mm thick in parts. The motherboard tray, which is also quite solid, has a number of cutouts for cables. Although they are not lined with rubber grommets that doesn't matter as the edges are very smooth.
While there are cutouts for cable management, In Win somehow overlooked the all-important CPU hole in the motherboard tray. This huge oversight can be corrected with a little modding, but for the price we would have expected In Win to do most of the work for you.
In our mind In Win has also let the tòu down a bit with the pre-installed wiring. While much of it is braided and looks great, the ends of the fan cabling aren't and the method that In Win uses to connect all fans up to the controller is extremely messy. Again, for the money this is something that should have come pre-installed all neat like.
The good news however is that behind the motherboard tray there is loads of space to hide cables, though those fan cables we just spoke of cannot be hidden here due to the location of the fan controller.
Given that the tòu is meant to be a show piece we understand why they have taken a very minimalist approach inside and why there is only room for three 3.5" drives. This is not a server style case and cramming it full of hard drives would just detract from the design.
Moreover, three 4TB drives will allow for a system storage capacity of 12TB, which we feel is plenty for gamers and power users. Any more than that and something like a dedicated NAS is a much better option. There is also room for a pair of SSDs as well so keep that in mind.
