Inside the Enthoo Primo
With one glance inside the chassis, it is obvious that it is as unique as the outside is. Take a moment to absorb this compartmentalized design as I take you through and point out all of the offerings and show you just how well thought out this design really is.
Near the top, but set down far enough to make sure a radiator and fans will fit above them, you have the five tool-free clips that will hold in the 5.25" devices. There is also the option to install heavier things like reservoir pump combination units in with screws for added security.
Where I would typically expect to be seeing a stack of hard drive bays, all you see from this side of the chassis is the large steel panel with a Phanteks plate that sort of reminds me of the InWin plates found in the D-Frame.
The motherboard tray has plenty of room for anything up to an SSI EEB, offers plenty of wiring options, and additional places to tie the PSU wiring to. On the right there is a reservoir installation piece that covers the motherboard wiring as well. This will conflict with longer air cooled video cards, and is removable to work on, or to leave room for the expansion cards - the choice is yours.
Below the motherboard tray there is a shelf to block the view of the PSU that goes in behind it, a modders dream in my opinion, as everyone covers them anyways. There are two holes to pass wires through and room on the floor for this 140mm fan and two other friends, or if you remove the hard drive section, you can set a quad radiator in here as well.
In the back of the chassis you can opt for this 140mm fan or use a 120mm radiator and fan if you want to. Next to the seven expansion slots that use thumbscrews for mounting, that vented area is another place to put a shorter reservoir.
