Ok, link fixed. I had a slash on the end.
No idea on quality though it's 1.5mm aluminum so about 25% thinner than the aluminum cases I have on hand. That might not make a difference. It says it'll hold a 2.5", 3.5" and a double-slot video card. A SFX PSU with the right mounting bracket would probably be best or a picoPSU with the right mounting plate.
It look like a nice alternative to the Lian-Li PC-Q07/Q11 if you don't need an optical drive.
These guys used to make a case very similar to the Silverstone ML-03B but all aluminum, no plastic. Unfortunately, they discontinued it
