Inside the Lian Li PC-B70 Full Tower Case
Lian Li uses a bit different way of keeping the side panels in place. Loosening the thumbscrew allows the release mechanism to slide back, allowing the removal of the side panels. Both the right and left side panels release in this fashion and once the mechanism releases the doors almost "pop" apart at the top for easier access.
Removing the door panel and reversing it allows me to point out a couple things. Remember the "dimples" on the outside images? As you can see, they are due to the inner supports and mounting hardware for the panel. These supports surround an open celled foam mat that has been applied to the panels.
My first look into the PC-B70 gives a large impression of overall space inside, accentuated by the reflectivity of all the aluminum exposed. Lian Li securely tapes the hardware box to the graphics card support bar, in order to keep the hardware in place during shipping. Considering the abuse my sample took in traveling, this is yet another testament to Lian Li's attempts to provide a perfect chassis upon delivery.
Starting off with the top, right corner of the interior, we get our first look at the new optical drive mounts for these five 5.25" bays. Releasing the tab on the right allows the "bar" to open out and to the rear. At this point you slide in a drive and align the holes, then lock them back into this position.
The bottom right corner of the PC-B70 houses the two 140mm intake fans that also blow across the seven tray 3.5" drive rack. These trays are isolated with rubber "washers" that rest in the rack itself, keeping vibrations created by the hard drives at bay.
The top left corner of this chassis houses yet another rack for 3.5" drives. This rack is backed with a 120mm fan to draw air across these drives while removing interior heat at the same time. Just below is another 120mm with a fan guard screwed into the chassis for a more standard rear exhaust. Both of these fans can be powered by 3-pin or 4-pin Molex connectors.
The lower left corner shows a few things worth mentioning. Not only are the expansion slot covers vented, they are held in with a very strong screw less mounting mechanism. The mechanism is easy to operate, but does require a bit of force to lock into place. Below these is the opening for the PSU installation. Lian Li also vents the floor of the chassis to allow the power supply to be able to be mounted fan down on top of the shelf-like supports.
Removing two Phillips head screws, the graphics card support can be removed for easier installation of the major components. Removal of this support also allows a better view of the motherboard tray. This tray has cut-outs for both wire management and a rather large opening for CPU cooler back plate mounting. As an additional bonus, this tray is in fact completely removable, as I will show a bit later.
