Who this is for
The ModCase Dock is a niche product. Buy it if:
- You game primarily docked (TV / monitor) and rarely take the Deck portable
- You like the aesthetic of a "permanent" Steam Deck setup
- You appreciate RGB / display lighting
For users who frequently switch between portable and docked play, the standard JSAUX HB0603 at $39 is a better choice — quicker to dock/undock and you keep the Deck's portability fully intact.
Trade-offs vs standard dock
Wins:
- Built-in stand (no separate stand needed)
- Cleaner cable management (everything routes through the case)
- Looks like a "real" mini console when set up
Losses:
- $80 more than the HB0603 for similar dock specs
- Adds bulk to the Deck for portable use
- Steam Deck specific (not transferable to other devices later)
