Installation
The installation was a breeze, and the ejection mechanism makes it really simple to remove and install drives. You can use the screws included, or you can use the clips for a tool free installation if you intend to do a lot of drive swapping. The clips were easy to remove and install, and they felt sturdy enough to hold the drive in place. You’ll know for sure when the drive is seated inside the NAS securely when you hear the reassuring click sound when you press the lever like cover of the drive holders.
Internal
The top case of the 1513+ is held by 5 screws at the back. Removing the top involves a bit of gentle sliding and maneuvering.
This unit is using a mini ITX power supply made from Delta, model DPS-250AB-44 B. There is a RAM slot that supports another 2GB, bringing the total to 4GB of RAM. I tried putting in a 4GB piece but the system refused to boot up since there is a 4GB total system RAM limitation. There is also a plastic shield probably to prevent any accidental shorts. RAM installation is easy, as the only thing you need to do is align the RAM properly and push it in place.
The back of the unit is equipped with 2 fans of 80mm size. The fans are 2900rpm, but it works between 1500~2500 rpm to achieve a lower acoustic levels. It is easy to remove, with 2 screws securing each fan in place. This is an important feature as it allows quick replacement of faulty fans during operation, or for those who want more powerful fans can replace it with aftermarket ones with higher CFM.
