Had this plan inspired by the sbbn049 Tuna that got realized thanks to this case and the T1000 bezel, it's absolutely beautifully made.
Everything fits perfectly and the finish is very good.
Combined the Tuna case with the T1000 bezel and it's super nice. This mod wears exceptionally well for the diameter the numbers say it is. Absolutely recommend for anyone considering a Tuna build.
Great case, awesome customer service!
Did a build in this 6105 conversion case and I'm really satisfied with the quality and tolerances.
