// 05 — Built different. By design.

What makes
ERIX different.

Designed through five iterations and six months of daily use. Every decision earned.

01

Single-fan thermodynamics

A shaped internal contour directs airflow through — not around — your components. One 140mm fan does the work of four small high-RPM fans, quietly. Zero throttling across 60 minutes of synthetic stress.

Fan 1× 140mm · standard mounting
Acoustic 43 dBA at GPU load · 90cm
02

Full-size GPU. No risers.

Full-length dual-slot GPU and full-size ATX PSU mount natively. No PCIe risers, no extenders, no adapters required. Standard mounting patterns throughout — build with the parts you already have.

GPU 245mm × 139mm · 2.5-slot
PSU ATX 150×86mm · SFX via adapter

Designed for 256mm beds

Every part fits on the most common consumer FDM print bed. No exotic printer required. Parts are oriented for minimal support material, and print settings are included in the assembly guide based on six months of testing.

Bed required 256 × 256 × 256mm min.
Material PLA blend · brass heat-set inserts
05

Clean assembly. Hidden screws.

Screws hidden by design. Logical, documented build sequence. Side and top panels remove independently so you never have to dismantle the whole chassis for maintenance or upgrades.

Access Side · top · front panels
Fasteners 26 hex · 4 fan screws · concealed
06

Structural. Not decorative.

Custom PLA blend with brass heat-set inserts and stainless steel fasteners. Functional carry handles rated for transport with a full build inside — built for LANs, the office, wherever you take it.

Weight ~1.24 kg printed · ~12.7L volume
Handles Dual · rated · zero flex
