As I said I am making the switch from a full ATX system to a mini ATX system so I definitely needed a new motherboard. I went with the DFI LanParty Jr. P45-T2RS, which is unlike most other mATX motherboards. It has pretty much all the features you would want in a full ATX motherboard, but crammed into a mATX board. One thing that is really nice about the b-Envi is that it has a removable motherboard tray. Just remove 2 screws on the back of the case and the tray will easily slide out.
Installing the motherboard is quite simple since the standoffs are already installed. Next you can install your video cards and other PCI cards. You will also notice that I am using the stock Intel cooler. This is because you can only fit low-profile coolers inside this case. There are only a few other coolers that I know of that will fit inside this case.
Next you want to install your hard drives. You can remove the hard drive cage by taking out 2 screws then sliding it out. Once it is out you can install your hard drives. Then simply slide the cage back down in and screw it into place.
To install your optical drives you will need to remove the front bezel of the case. There are 4 clips that hold it in place. Once you have the front of the case removed you can slide in your optical drives. You are probably going to want to connect the drive completely because things get a bit tight once you install your power supply.
You are able to fit a normal-sized ATX power supply into this case, although things get really cramped. I used the Tagan BZ Series 900W power supply with the b-Envi and things were very close. Bgears suggests you use their b-tarantula modular power supply with the b-Envi.
Once I had everything installed things were a bit cramped, especially the extra wires. There really is not much room for hiding wires so things are kind of a mess inside. You also want to try to keep wires clear on the exhaust fan and your CPU cooler.
I did have some issues when trying to put the top panel back on the case. The left side of the panel would not go into place right. I’ve had this happen on other cases before. I did everyhting I could to make it work, I check if cables were blocking it, took the top off and started all over, but I could not get it back on correctly. Now the top of the case was install but because of the left side there is a small gap between the front bezel of the case and the side panel on the left side.
