The terra has a shiftable midplane, so you might have to calculate the minimum setting you would need on both sides (CPU cooler side ande the GPU side) and be sure that it will fit. If Noctua said it will fit, you can be sure that it will, but they don’t know how thic your GPU is gonna be.
Looks great otherwise, the terra is beautiful. Be mindful, if this your first SmallFormFactor build, the performance might be a bit less then if built in a roomy ATX mid tower instead. I was kind of surprised by that on my first SFF(Factual Node 202), thats why I mention it.
It takes an extra second to read/see what you are supposed to do, but after that I have to agree with you, I also like the placement and actions required to replace the batteries.
