Box mod suggestions built with more premium materials?

Currently using a Thelema Solo that's been my daily driver for years. Looking to upgrade to a new mod sometime in the near future, Looking for something built with more premium materials, i.e. metal construction if something like this exists.

I see some really nice mechanical mods out there and would love to find something with an aesthetic like that, only not a mech mod, just a normal box mod, preferably single battery. I would consider trying something new as long as it's easy to use and doesn't require considerable effort. Any suggestions are very welcome. Thank you!
