To get into the Bullet BH7 you have to remove the 14 screws that hold the top panel on. Once the screws are removed pulling it off wasn’t hard with our handles but I would imagine it might be harder without the handles unless you want to get smudges on the side panel window. Like I said before the case is split into two halves horizontally. The split it right at the split for the two clamshell orange panels. The interior has the same flat/satin black finish as the front and back of the case.
The dividing panel is actually the motherboard tray as well as a second wire management panel. The motherboard tray is held on with four screws and the second panel has two, so they are both easy to remove and work without outside of the case. That also gives you access to the bottom half of the case. The motherboard tray has a very large CPU back panel access hole for installing a new heatsink later on with the motherboard installed. There are pre-tapped holes for motherboard standoffs to fit a variety of options. You can run ITX, mATX, ATX, and in some cases E-ATX. There is also support for SSI-CEB. With E-ATX board sizes do vary a lot so you have to be completely sure to check the measurements. They also slipped in a rubber pad for additional support right next to where the top PCI slot on most boards would be.
The smaller panel has a gap most of the length of the case for wires to come through. This panel can be flipped to move the wire holes over to the edge of the case if needed, but if you install any fans in the front they will block the wire access if you have it flipped. There are motherboard standoff holes on this panel as well for when you have it flipped to support some wide E-ATX boards.
Fr cooling there is a top mounted fan mount that holds two 120mm fans. This matches up with the vents on the top panel of the case as well. You can mount a 120mm or 240mm radiator here although I will say that it is a very tight fit once you add in fans, that’s not even counting trying to fit any other components. The case was designed for air cooling and frankly, even that will have you measuring and making sure things fit. The official support is for a 146mm cooler height but I’m not sure if that includes having two fans in the mount above or not.
The last optional accessory that I picked up for our case where the LED lighting mounts. You get two, one for each side of the case and you can mount lighting strips on any of three angles. The mounts hold a 30cm strip just about perfectly and the different angles depend on what style of lighting you want.
The front mounted fans have an interesting mounting plate on the inside of the case to keep from having any fan mounting screws on the outside. It is held in place using four nuts and two hold-down clips down at the bottom. When you pull the plate out you can mount two 120mm fans or if you want you could remove the plate altogether and use the front slots as a way to peek inside of the case.
I covered in on the exterior section but the back of the top half of the case has the rear I/O panel hole, the 7 PCI slots, and the honeycomb venting covering the rest of the free space. The PCI slot covers are all solid and held in place with thin thumbscrews with a Philips on top.
Pulling out the 6 mounting screws to take the motherboard tray and the wire panel off gives you full access to the bottom of the case. I imagine once you get your PC built you are going to want to avoid having to dig this deep into it so make sure you take your time with anything in here, especially wiring so you don’t have to do it again later.
The bottom of the case has a slightly raised panel to support the bottom of your power supply. It has ventilation for the power supply intake fan. It looks like the case could support a long power supply if needed, but it would really make things tight for wiring, especially up against the front I/O wiring. The other side of the case comes with a black hard drive bracket with three mounting points on it. Along with the SSD adapter, you can install your 2.5 or 3.5-inch drives here. The plate that it is mounted to has mounting holes for a second hard drive rack or their optional accessory mounting plate for something like a water pump.
The removable bottom panel is a good way to gain access to the bottom of the BH7 once you have everything built. It’s also the only way to have good access to the hard drive cage. The cage is mounted to the plate and has the three mounting points. It uses rubber mounts screwed onto your hard drive to cut down on the vibration.
The headphone connections and the two USB 3 ports are all one unit when looking from the back. The power button is a completely standard anti-vandal switch, even from the back. So the cabling for the power switch is all custom sleeved with a black sleeving and then the rest of the I/O connections are all a smooth black finish.
