Both panels on the door are hinged and held in place by magnets. While this is nice, as it provides easy entry into the chassis, stronger magnets would have been welcome. As these panels are on pins, you may pull them off completely and move them out of the way during the assembly process.
The interior of the CUT593 looks pretty traditional with a few cutouts for cable routing. As you can see, the sleeved cable components are pre-routed, but for whatever reason, pointing in the wrong direction out of the box. This means that you may have to do a little bending and massaging to get them into the right angle to connect to your motherboard. A metal shroud hides the power supply. You may install up to three fans on the shroud if you like, but that means that you have to remove the 3.5" tray that ships with the chassis.
Speaking of that tray, it is held in place by a single screw towards the back of the case and will block the user from easily reaching the connectors at the bottom edge of the board. The way it is secured inside the case means that you will always have to remove your GPU just to remove the tray to add or swap drives. Overall, there is really no reason for this tray. FSP could just remove it and advertise the fact that the shroud allows for additional cooling instead. Towards the front, there are two mounting positions for SSDs with a central opening to route cables through. It would have been nice to see a grommet here, especially as one of the unique selling points of the CUT593 is the clean, integrated cable management.
Behind the motherboard tray, the two power cables are held in place by plastic clips, with one routed to the left and the other into the top. These cables sit on top of a cover, which feels odd, as there is really no way to use the space underneath it anyway. You may flip down the bottom cover to reveal the area underneath the shroud. This panel is hinged, which is a nice touch, but unfortunately also uses magnets which are simply too weak to keep it in place properly. The whole contraption with the white power cables can be pulled off the chassis, again using clips and magnets to hold into place - which, as we will see later on makes it near impossible to secure in place perfectly.
FSP added a third 2.5" hard drive tray on the back, which is visible through the glass panel. This is a nice touch, but unfortunately the choice of tray will hide most of your drive. If a different style tray had been used instead, users could easily have had their whole, possibly RGB equipped SSD shown off instead, this is a relatively minor gripe, however. On top of that, plastic isn't the best choice of material for an element that is meant to be shown off.
Underneath the shroud, you will find a HDD cage that is capable of holding up to two 3.5" and one 2.5" drive. The presence of this really cements the fact that FSP could remove the one tray on the interior of the case without negatively affecting the overall appeal of the CUT593. The tray is held in place by a thumbscrew and metal clip, as you have to pull it out to add drives. In the front, you will find the three intake fans. These are sitting on the exterior of the frame, which is a nice touch as it provides an unobstructed view of them from the front while also leaving as much room as possible on the interior. That said, the honeycomb metal pattern should really not be there at all, to provide as much airflow as possible.
In the rear of the case, starting at the bottom, the PSU bay offers foam pads as an anti-vibration measure. There is ample space for powerful enough units to fit, by simply sliding it in from this side. Above that are the seven expansion slots, with the individual, reusable covers which in turn are held in place by classic screws. In the very top, you will find another ARGB equipped 140 mm exhaust fan, which is a nice touch.
Looking at the ceiling, AIOs of up to 280 or 360 mm size will fit, but they will also block access to cable routing at the top for the most part. From this angle, you can clearly see the two unique power cables sticking out to be attached directly to your board.
The wiring within the FSP CUT593 is all run-of-the-mill with black sleeving. As FSP does not include a PCB for ARGB/PWM, you are left with a bit of a daisy-chained cable mess that you will have to deal with, unfortunately.
