Installation is pretty quick and easy with the Mana 137. For most standard motherboards you won’t even need any motherboard standoffs; just simply secure the motherboard with screws. Installing expansion cards may be confusing at first.
If you read this review, you’ll know that there is only a single screw holding all of the expansion cards to the case. Now this seems unreal, but it’s true. The one screw, on the back panel, holds a black locking plate. Remove this and you can install your expansion cards without any screws.
The In Win Mana 137 supports a lot of drives, despite its small size. To install one of the two 2.5” drives, just simply flip the case on its side, place the drive over the holes and attach four screws to secure it.
The tool-free system in this case for 3.5” drives is unique, but yet effective. All you have to do is attach four special screws to your hard drive, which can be done by hand.
Then just simply slide the drive into its slot. The yellow plastic acts as a locking mechanism for the drive. It’s surprisingly pretty sturdy for such a small device.
Installing a 5.25” drive is just as simple, if not simpler. Just remove the cover by pressing in on the two side clips. Then remove the tool-free device, slide in your drive and lock it up with the tool-free locking device.
