Two systems in a single PC case – a very niche thing to build, but certainly doable. Whether it’s for gaming and rendering simultaneously, integrating a NAS with a PC, or maintaining separate systems for security and leisure, dual system builds offer innovative solutions. Due to the rising demand, we have a variety of best dual system PC cases available today. From budget to high-end, combinations of ATX with Mini-ITX, or even two full ATX systems, there’s a suitable option for everyone.
However, some require additional components like Phanteks’ dual system upgrade kit, specific dual-system PSUs, or even a PSU power splitter – though we caution against the latter due to safety concerns. For compact power solutions, explore the best SFX power supplies. Interested in an integrated gaming and streaming system? Pair it with the best CPUs for streaming. Lastly, if optimal cooling is your priority, don’t miss the best airflow PC cases for superior thermal performance.
MetallicGear NEO Qube: Best budget dual system case
The NEO Qube from MetallicGear, a subsidiary of Phanteks, draws parallels with Lian Li’s O11 Dynamic but offers dual system capabilities at a competitive price, making it a standout in the best dual system PC cases for budget-conscious users. Mirroring the O11’s features, it supports excellent water cooling, vertical GPU mounts, and spacious interiors with efficient heat dispersion. However, build quality could be better. It accommodates an E-ATX main board and an ITX secondary system, powered by the Phanteks Revolt X series PSU. The case fits up to nine fans, three 360mm radiators, and eight drives, with specific cooler and GPU clearances. The secondary system leans towards low-profile components, and the front I/O is well-equipped with USB ports and an RGB button.
Phanteks Enthoo Mini XL: Best mATX dual system case
In the realm of the best dual system PC cases, the Phanteks Enthoo Mini XL stands out for those wanting to combine an mATX and an ITX board. Despite its grand stature, this case supports two full-sized GPUs, substantial CPU heatsinks, and dual PSUs – though opting for the Revolt X power supplies might be better than using the provided PSU splitter. Thermals are commendable, with space for up to thirteen 120mm fans and room for various radiators. Generous clearances are given with 215mm for CPU heatsinks and up to 410mm for GPUs. Storage options are vast, accommodating eight 2.5” drives (expandable to 14) and three 5.25” bays. Each front panel features USB 3.0 and audio jacks. The only setbacks are its dated acrylic side panels and the potentially hazardous PSU splitter.
Phanteks Eclipse P600S: Best quiet dual system case
For those pursuing the best dual system PC case with a silent edge, the Eclipse P600S by Phanteks is a prime choice. This silent case offers versatility, reminiscent of the Evolv X’s internal layout. An essential dual system expansion kit allows for a secondary system installation at the top.
Thermal efficiency is decent, fitting radiators up to 420mm, 360mm, and 140mm fans. Intending a GPU for the ITX secondary system? A GPU riser card is a must, enabling a vertical GPU setup. Accommodating up to seven 120mm or with three pre-installed 140mm fans, storage is adaptable with slots for four 3.5” and three 2.5” drives, expandable to 13 drives overall. There’s a 190mm clearance for CPU coolers, and GPUs can extend up to 435mm. Secondary setups should opt for a slim cooler. For connectivity, the front panel offers two USB 3.0, one USB-C, and audio jacks.
Phanteks Enthoo 719: Best full tower dual system case
The Enthoo 719 from Phanteks stands as the best full tower dual system case currently available. Supporting both an SSI-EEB and an ITX board, it’s powered by a single PSU, although it intriguingly supports two PSUs—requiring a choice between dual PSUs or dual systems, thus limiting you to Revolt X power supplies for the latter.
Secondary systems are installed below the main board area, necessitating a vertical setup for the secondary GPU. Impressively, both GPUs can be as long as 503mm, with primary CPU heatsink clearance at 195mm. If utilizing a secondary GPU, heat sink clearance is reduced to 60mm or 80mm. However, with support for multiple 480mm radiators, a custom loop cooling both systems is feasible.
For air cooling enthusiasts, it accommodates up to fifteen 120mm fans. Design-wise, the case marries old-school front panels with modern touches, like a glass side panel and subtle RGB. Its front panel boasts four USB 3.0, one USB-C, and dual power buttons. Finally, storage capacity peaks at twenty-three drives.
Corsair Obsidian 1000D: Best dual system PC case for water cooling builds
For those seeking the pinnacle of water-cooling dual system builds, the Obsidian 1000D from Corsair is unparalleled. Arguably the best dual system PC case for water-cooling builds, it supports one ATX and one M-ITX system, accommodating two power supplies (ATX + SFX) and dual 480mm radiators. Alternatively, outfit it with an astounding 18 case fans.
Exquisite build quality shines through with two expansive smoked tempered glass panels, reminiscent of the iconic monolith from 2001: A Space Odyssey. Also notable is the integrated fan controller. Yet, some might find its eleven storage bays (six 2.5”, five 3.5”) limiting, especially for those considering a workstation plus NAS combo. For optimal NAS housings, see our best NAS cases. Lastly, the 1000D’s front panel impresses with four USB 3.0 and two RGB-illuminated USB-C 3.1 gen2 ports.
Thermaltake Core W200: Best dual ATX system case
Thermaltake’s Core W200 stands out as the best dual system PC case for those wanting dual ATX setups in one frame. Designed for exceptional liquid cooling, it supports up to two 600mm radiators and fits GPUs up to 470mm with ample storage for twenty-four drives.
