Hardware Installation and Clearance Compatibility

Raijintek Styx

One of the best things about the Raijintek Styx is that screws hold everything in place so it is highly moddable and can be taken apart completely if needed in order to repaint, customize or simply install the components. This includes being able to remove the motherboard tray entirely for installation, a feature that is lacking in most modern chassis designs.

Bottom mounted radiator:

  • Bottom 120mm fan supported. There is too little space for 120mm radiator with standard 25mm thick fan however because the motherboard is in the way.

Rear Radiator:

  • Rear 120mm fan / radiators supported

Top Radiator:

  • Total space from the ceiling to before the motherboard begins is 55mm so a radiator up to 30mm thick can be used with a push or pull fan. More space is actually available since the mount is centered and there is an allowance for an overlap without touching the bottom of the motherboard components. Make sure that all the connectors are plugged in first though because some of the headers can be obscured when a thicker radiator is used.

Video Card clearance:

  • Total length stated officially is 280mm, but obviously from the picture above, a 305mm long graphics card fits as well with a 140mm deep PSU. The power supply used will determine clearance compatibility as power supplies (even modular ones) with connectors in the way will limit the video card length usable. Some modular units can be used if the necessary headers are on the left side and on the top bank. This Silverstone ST75F-PT power supply for example has the PCI-E power and 8-pin EPS12V connectors obstructed by the 305mm long graphics card but the peripheral connectors and 24-pin connector plus sensor wires are not.
  • 280mm is the limit for graphics cards before it blocks the PSU connector, 265mm clears the connectors but 250mm is the hard limit for actual PSU housing clearance. Power supplies that are 170mm or longer are limited to 250mm long graphics cards (see photo above).
  • For cards greater than 250mm in length, an ATX power supply that is under 150mm deep or an SFX power supply with an ATX adapter mount is advised as its compact depth provides significantly more clearance. Some SFX models for example are only 100mm deep compared to the most compact ATX PSU which is 140mm deep.

CPU Tower coolers:

  • Official CPU heatsink height clearance support is up to 180mm. The Noctua NH-D15 can fit comfortably with room to spare, although it is recommended to plug-in the 8-pin EPS12V connector first as it will be impossible with a large heatsink on the way otherwise. For extra clearance during installation, removing the rear 120mm fan temporarily is suggested until all components have been installed.
  • The backplate cut-out is useless for any micro-ATX motherboard because 1/3rd of the backplate is blocked.

PSU Installation:

  • PSU length is dependent on video card length. If video card does not encroach on the PSU area (280mm long video card or under), PSU length is a non-issue. If using a 305mm long video card however for example, even a compact 140mm deep power supply will be obstructed if it is a modular unit (140mm PSU body+~10mm connector+partial few millimeters accounting for video card sag, extra PSU enclosure height, video card backplate, etc).

5.25″ ODD installation:

  • There is room for a slim slot-loading optical drive on the front facing the right side panel. It does not support tray-loading slim drives but it can be modded to do so by enlarging the opening.


3.5″ HDD installation:

  • Users can mount up to two 3.5″ drives on the HDD side panel plus one more on the floor of the case. Clearance is very tight when installing on the floor however, so it is advisable to install the drive first and plug-in the cables before installing the motherboard, especially if there is a large CPU cooler on the way.

2.5″ installation:

  • Up to two 2.5″ drives can be installed on the same side panel plate that the 3.5″ HDD drives use.
  • Two more 2.5″ drives can be installed behind the motherboard tray.


Cable management:

  • The space behind the motherboard tray is very tight at only 10.5mm. An ideal solution would have been if Raijintek lessened the 180mm CPU height clearance by just 10mm as even the Noctua NH-D15 is 165mm tall, it would have made the cable management clearance 20.5mm.
  • There is a routing hole for the 8-pin EPS12V but it is half-way obstructed by the motherboard. Only slim or sleeved cables can be routed here once the motherboard has been mounted and the connector itself can only be passed through at that point with the two 4-pin headers pushed through sideways (since the locking mechanism will prevent it from going through).
  • There are four loops for securing cables with a zip-tie behind the motherboard tray.
  • The top part of the motherboard tray (which in this case is the bottom side of the motherboard) is completely open so cables can be passed through freely here.
  • Two large cable routing holes are available for moving cables between the main chamber and behind the motherboard tray.
  • The slim ODD mounting brackets can be removed if not in use so that extra cables from the power supply can be stored in its place.

  1. Hi!
    How are things going with a 160mm deep modular PSU in regards with the GPU clearance?

  2. Compatibility will depend on the model of the modular PSU because of the placement of the connectors. The Cooler Master Hybrid for example had the 24-pin and PCIE at the bottom row so it will be obscured with cards longer than 250mm, but some modular power supplies only have some of the peripherals at the bottom row, but have all the essentials at the top. 160mm is the absolute physical limit without factoring in connectors (just enclosure to card, also not factoring in sag, etc). If the card is long, the tip of it will be sitting partly of the 160mm long PSU. For a 160mm PSU, a non-modular would actually provide better clearance (although a lot more extra cables to cable manage).

  3. Thanks!
    I’ve been taking a look at Corsair RMx/RMi series which are 160 mm deep and have the modular connectors similarly placed as the Silverstone PSU you have used, so that leaves about 280mm for the video card.
    I wished Rajintek made the case a bit more compatible with 160mm deep modular PSU’s, as there are to few great choices below this size.

  4. Unfortunately I do not have a 650W RM series on hand to verify the clearance but Watercooled.ch used a Thermaltake DPS-G 650W (a 160mm deep PSU as well) on their review and you can see there the clearance on their assembled build photo (link below). The video card they used has a shorter PCB and had a longer heatsink so you can see that the PCB with the sag would actually be touching a 160mm if the PCB was as long as the heatsink: http://www.watercooled.ch/raijintek-styx-case-review/

  5. It is a little bit pricier than ATX, but you can also check out SFX power supplies as they would be the most comfortable as it is only 100mm deep. Although some companies don’t include the SFX to ATX adapter out of the box. I know Corsair doesn’t but Silverstone does. Amazon lists the adapter as worth $20 which is too expensive IMHO. Corsair should start bundling it in their SFX units like Silverstone: https://www.amazon.com/SilverStone-Technology-Universal-Bracket-RL-PP08B/dp/B01BYB33J8
