The inside of the case is rather roomy and there is nothing getting in the way. The motherboard tray is not removable, but it is large and can accommodate most motherboards.
The front of the case includes four 5.25" bays and and seven 3.5" bays. There are places for tool-less devices to hold the drives into the case, but XClio does not include them. They are listed as optional on the features list, but I am checking to see how the user can actually acquire them. For the rear of the case the 3060 Plus uses the kind of PCI covers that are attached to the case and need to be bent and twisted to be removed. I dislike these very much: they are difficult to remove without bending the case, once they are removed they cannot be replaced, and they often have a sharp edge where the old plate was removed.
The front bezel comes off with a tug on the lower edge of the panel, and behind it the front fan location(s) can be seen. XClio lists it as capable of housing four 80mm fans, one 120mm fan or one 140mm fan, and it looks like there is also a spot for a 92mm fan in the center. Again, these stamped grills are very restrictive, and there are several places where more holes could have been added. The back of the front bezel shows the bay cover for the optical drive and how it works. The part on the bezel that acts as the button for the tray eject is movable to tailor the cover to match the particular drive installed.
At the bottom of the front bezel are the wires for the switches, lights and ports. The wires may seem like a lot, but it is the standard amount for most cases, aside for the Power light. Since the ring around the power button lights up to show system power, XClio uses two LEDs to perform this function. These LEDs are connected to a standard four pin Molex connector, but there is no pass-trough to connect another device.
Finally, on the back of the left side panel the 360mm fan can be seen. There is nothing on the inside to block the airflow, which is good, but there is nothing to protect the components inside either. The user needs to make sure no wires or water tubing will come in contact with the fan. XClio also uses a four-pin Molex connector for the fan, but it does not have a pass-through either.
