Fractal Design has announced four new products in a single release: Summit (a new premium ATX case series), Define One (a desk-focused addition to the Define family), Radius (next-gen AIO liquid coolers), and Refine 2 (second-gen gaming chair). Full MSRP pricing and specs were included in the announcement for all four lines, so here’s the breakdown on what’s actually new and who each one is for.

Quick Verdict
This is a coordinated, multi-category launch rather than a single flagship product, and the pricing is aggressive across the board — Define One at $154.99 and the standard Radius coolers starting at $79.99 both undercut a lot of the competition on paper. Summit is the most interesting of the four thanks to its wood-panel construction, a first for Fractal at this price point. Refine 2’s $639.99 price tag puts it firmly in the premium gaming chair bracket, competing with established ergonomic brands rather than budget options.
Who Should Buy This
- Summit is for builders who want a case that reads as furniture first and PC case second — think living room or home office builds where aesthetics matter as much as thermals.
- Define One is for anyone who wants the acoustic-dampened, closed-front Define experience but built specifically around a desk-based gaming rig rather than a workstation or NAS build. If you already own an older Define case for server duty, this doesn’t replace it — the original Define line continues for that use case.
- Radius is for buyers who want a straightforward 240mm or 360mm AIO with modern conveniences (rotatable pump cap, browser-based RGB control) without needing to install another vendor’s control software.
- Refine 2 is for anyone shopping in the premium ergonomic chair category who wants Scandinavian design language over the more aggressive “gamer” look most competitors default to.
Pricing and Spec Breakdown
Summit (ATX case) — $169.99 (Chalk White Solid, Chalk White TG Clear Tint, Black Solid, Black TG Light Tint, Blackout TG Light Tint) / $199.99 (Ambience Blackout TG Light Tint, RGB). Multi-layered oak or walnut panels, three pre-installed Momentum 14 fans, GPU clearance up to 425mm, radiator support up to 360mm front and top, reverse-connector motherboard compatible.
Define One (ATX case) — $154.99 flat across all four variants (Dark Solid, Dark TG Light Tint, Light TG Clear Tint, Light Solid). Aluminum side intake vents, sound-dampened front and side panels, three pre-installed Momentum fans, GPU clearance up to 368mm, radiator support up to 360mm front / 280mm top, reverse-connector compatible.
Radius (AIO liquid cooler) — $79.99 (240, standard) / $89.99 (360, standard) / $89.99 (240 RGB, Black) / $99.99 (360 RGB, Black or White). Pre-installed Dynamic 3 fans, tube-integrated cabling, articulating tube connections, rotatable pump cap. RGB models add Adjust Pro browser-based control for pump and lighting — no separate software install required.
Refine 2 (gaming chair) — $639.99 across Fabric, Mesh, and new Hybrid materials, each in Dark or Light. New flexible dual-pad lumbar support, lockable 4D armrests, expanded adjustment ranges, updated headrest and cushioning. Hybrid combines a mesh backrest with a cushioned fabric seat.
What We’re Waiting to Confirm
- Exact regional street dates — Fractal’s release lists pricing as an estimate “subject to change without notice due to currency fluctuations,” and no specific ship date beyond the announcement date was given.
- Real-world thermal performance for Radius against established 240mm/360mm competitors — the spec sheet covers fan and pump hardware but not benchmarked noise or delta-T figures.
- Airflow-versus-acoustics tradeoffs on Define One now that it’s positioned specifically for gaming builds rather than storage/server use — Fractal’s marketing emphasizes both quiet operation and aluminum intake vents, and we’d want to see how those balance in practice.
- Long-term durability of Summit’s wood panels under normal handling and climate variation, since wood paneling on a PC case is a newer approach for Fractal at this price tier.
- Refine 2’s actual seat time comfort — lumbar and armrest specs read well on paper, but chairs are notoriously hard to judge without sitting in one for an extended stretch.
Bottom Line
On paper, this is a strong, well-priced release across all four categories, with Define One and the standard Radius coolers standing out as the best value plays. Summit is the one to watch if case aesthetics matter to your build, and Refine 2 competes credibly in the premium ergonomic chair space rather than settling for gamer-chair styling. We’ll be following up with hands-on testing once units are available — check back for full reviews and benchmarks.
