Panel Option (Motherboard Side)
Color will correspond to "Panel Color" selection above.
Front Panel Board Connector
* This option connects both 3.0 A and USB C ports to a single motherboard header, recommended for AMD Ryzen 3.
**This style header is common on many ASUS, Gigabyte, and EVGA Intel Mini-ITX motherboards.
Riser Cable
* Bifurcation is recommended only for advanced users.
Bifurcation is the technology of splitting a single PCIe 16x 3.0 slot into two PCIe 3.0 16x slots with 8x bandwith on each.
Known supported motherboards include Gigabyte Z390 Auros, Z370N; ASRock Z390, Z370, X299, and X99; and most server motherboards.
Please confirm compatability with your motherboard by contacting sales@sliger.com before purchasing.
Power Supply Cable
* Standard power cable restricts GPU height to 133mm.
** Pigtail power cable mount does NOT restrict GPU height.
Handle Options
2x 3.5" HDD Bracket
* One HDD bracket limits case to a single 120mm or 140mm AIO / radiator in the top of case. See this picture.
** Two HDD brackets does not allow any radiators or AIO coolers to mount in the top of case. See this picture.
Bottom Fan to 3.5" HDD or 120mm Fan/Radiator Adapter
This bracket allows custom loops to be built with 1x 120mm radiator (27mm thick) and 1x 120mm x 15mm thick fan in the lower front position.
Prefilled 120mm AIOs are not compatible here as AIO hoses will kink on the chassis middle spine.
This bracket can also be used to mount one 3.5" HDD or 120mm fan. If using two of these brackets at the same time for 2x 3.5" HDD it is recommended to get at least one vented side panel as airflow may be constricted.
