This build trades the closed, heavy feel of a traditional case for an open frame, then leans hard into one color story: vermilion red against near-black. The centerpiece is Seasonic's FOCUS ROSSO limited edition PX1000 power supply, whose red-and-black PET braided modular cables run through the whole system like a power artery connecting every component. What follows is a look at how the hardware layers stack up — and the full parts list.

An Open Frame That Shows Its Layers

The XTIA Xproto-Z ROSSO limited edition chassis is the reason this build reads as a single sculpted object rather than a box of parts. With no side panels swallowing the internals, every layer stays visible: the TRYX PANORAMA ARGB 360 cooler up top, the MSI B850 motherboard behind it, the graphics card mounted low across the base.

The palette does the rest. Deep red anodized aluminum frames the black hardware, and the ROSSO branding glows from the power supply shroud in the same shade. From the side, the GeForce RTX badge on the Colorful iGame RTX 5080 ADVANCED OC sits almost like a signature line under the whole composition.

The Seasonic ROSSO Limited Edition Touches

The collab details run deeper than the power supply itself. The PSU's own fan grill arrives finished in the same red, its diagonal slats stamped with the Seasonic mark, and the XTIA × Seasonic branding is etched directly into the chassis — along the rear pillar and again along the foot of the base stand.

A brushed metal badge on the frame marks this unit as Limited Edition 003/100, a reminder that the ROSSO run is a numbered, small-batch release rather than a standard SKU. At the back, the perforated red panel and exposed I/O keep the open-frame layout honest: nothing hidden, everything part of the look.
