Opening up the Vengeance C70 there is lots of room. There are grommets in the wire routing holes in the motherboard tray, and the accessories box is tucked away in one of the 3.5 drive bays.
Both the 5.25 bays and 3.5” bays are tool-less. The 5.25” bay locking tabs are also made of steel. The 2.5/3.5” hard drive bays are separated into two groups of 3. The lower drive cage can be removed to allow for a 240mm radiator to be installed in the bottom of the case.
Both cages can be removed and fans installed on the front of the case to lighten the overall system weight if the user is not using them or would like to make room for water cooling parts.
The cages come with a 120mm fan attached to the inside face.
The trays are tool-less for 3.5” drives, if you use 2.5” drives they attach with provided screws.
In the rear of the case is the 3rd included 120mm fan. All the expansion slots have black thumb screws.
Moving around to the right side we can see behind the motherboard tray. The tray has a very large CPU cutout to allow for access to the backside of the CPU socket.
There is also plastic hold down straps for the cable management. There are also the standard loops for holding cables down wire ties. The straps simply snap into the motherboard tray. On the right side is also a thumbscrew for each hard drive cage.
What the frame looks like behind the front bezel.
The front bezel including the 5.25” bay covers are made of steel. There is a dust filter.
The dust filter is held in place with tabs on the front bezel. They also line up with the tabs that hold the front bezel to the case frame.
