We're not planning a 3 slot variant for Sentry right now, but who knows, if that's where the industry were to be going, then we might see if that makes sense, but only after we're running production properly for 2.0.
The issue with current 3 slot cards is that RTX chips are still on the old production node while having much more stuff inside and thus they make a lot of heat. This should change with next generation and I assume that current RTX generation is not going to be a future proof thing, there's going to be a lot changes there.
Getting back to your "3-slot Sentry" idea, we know there's a lot of things that this would enable:
- Taller CPU coolers, quite a lot of them, including for example wraith stealth fitting out of the box, taller noctua coolers, cryorig C7 not being so loud etc.
- Thicker package for AIO cooler, maybe even two slim fans instead of one.
- Mounting slim fans beneath the two slot GPU.
- Mounting two 15 mm 2.5" drives or slim ODD under the SFX PSU.
- Actual place for slim fans on the sides that could help exhaust hot air from GPU in horizontal position.
etc etc. But the issue of volume still stands - I don't think that we'll be able to compete against stuff like node 202 when we'll get close to the 10L volume because of the price difference we cannot change, until we have mass production running for at least one product and it sells. This size of ~7L is what we're focused right now and we want to make it properly. The whole idea of this project was to make a case that is true to the ideas of original steam machine and we're still on track with that.
What I'd be more keen to do when we're in full production, is a Sentry-like chassis designed around APUs, like the Ryzen 2400G, especially when 3400G is just around the corner (6 cores/12 threads + powerful IGP). I'm not sure though if this should be something to compete with inwin chopin OR should this be the same as Sentry in size and shape, but focus on the APU being water cooled by 240/280 AIO for a silent HTPC/light gaming rig.
On another topic, our Black Ridge order is pending delivery, so we should be able to check it out inside Sentry this week.
