Rails and Screws
Manual /Clear Window
The Poseidon comes with all the necessary documentation and extraneous parts that the case needs to install the motherboard and drives. The drives are all mounted within the case by plastic rails that lock into the slots provided for the various sized drives. You can then easily remove and reinsert the drives if need be without the need for a screwdriver. We decided to just go ahead and build a nice system since the whole point of the case review is to see how the case functions. Even though many cases tout the title tool-less, all of them require a screwdriver to install the motherboard and usually the rails that are use to mount the drives. The parts are machined so that everything comes apart and goes back together smoothly, some cases side panels are a real pain to get on, not so with the Poseidon, it just pops back on.
Installing the motherboard was simple, some people like the removable motherboard tray, but I find it unnecessary for the most part as just installing the stand-off screws and then sticking in the motherboard is easy enough in itself. Before installing the board we first changed out the rear I/O shield to the one that matched our board. The drive rails are attached in this case without the need of a screwdriver as the rails have pins that just push in to your drive so you can the stick them in their appropriate bays. The hard drives mount sideways making access to them much easier, which is a big plus if you really need to change out the drive quickly. We did a semi-custom job on this machine as it was not really for show, but more for go, so it didn't need to be all too fancy. Installation into the case was a pretty straightforward affair, with nothing to deter us in our task. It took us about an hour and a half to get the system like you see in the pictures below. There were absolutely no sharp edges, non compliant parts or other obstacles working with the Poseidon. If you are looking for something simple, yet ergonomic and easy to work with, the Poseidon fits the bill.
