ASUS has announced the Prime AP304 ATX PC case, and like many cases in 2026, it features a curved tempered glass panel; what’s different is that it’s got patented slot vent design which ASUS says is intended to optimize graphics card cooling. There’s also the RGB-laden version available as well, with four pre-installed ASUS Prime MR120 ARGB fans.

Aside from the curved side panel, the case generally sticks to the tried-and-true dual-chamber design with the PSU isolated on the bottom chamber. In between the two is where the slot vents lie, with three-sided ventilation structure that allows air to be drawn towards graphics cards. That’s probably designed with power-hungry GPUs in mind, and those usually are gigantic slab of metal inside the case, so there’s a reinforced GPU bracket and a tool-free slot clamp for installation as well.
The Prime AP304 supports graphics cards up to 420mm long and radiators up to 360mm, while the reinforced graphics card bracket accommodates cards between 300mm and 360mm long (it is secured with screws to reduce sagging, while the slot clamp allows tool-free installation). Maximum CPU air cooler height is rated at 175mm, with maximum PSU length at 200mm. The case includes an I/O panel at the top with a 20Gbps USB-C port, along with a 33mm cable management compartment located behind the motherboard.
The ASUS Prime AP304 ARGB is now available in Malaysia, priced at RM530 for the black edition and RM540 for the white edition.
Pokdepinion: While ASUS claims it’s patented, it’s not too different from many dual-chamber designs out there, is it?
