Maingear MG-1 Mk.II: powerful but costly, with cheaper alternatives

Maingear's updated MG-1 Mk.II can be built around AMD's Ryzen 9 9950X3D2 Dual Edition and an Nvidia GeForce RTX 5090 Founders Edition, and the chassis does a good job of showing off those components. It looks very nice and is very well built in many respects, but the case panels feel cheap and fiddly, so the visual charm doesn't fully match the everyday experience.

The review sample arrived with 32 GB of Kingston DDR5-6000 CL30, a 2 TB Samsung 9100 Pro Gen5 SSD, an MSI MAG X870E Tomahawk Max PZ motherboard, and Maingear's Epic 360 AIO cooler. That specific configuration tallies to around $7,273 (excluding shipping), while Maingear's Ultimate prebuilt is listed at $7,199 and the simplest MG-1 starts at $2,491.

The RTX 5090 alone pushes a large share of the cost, and the GPU, CPU, memory and storage together account for roughly 73% of the total price. The new front panel is a highlight: magnetic, swappable, and backed by three 140 mm intake fans that give the system good airflow.
