Rollei 35SE, Kentmere 400 in Rodinal.
Mine is a series of continous upgrades from my first build nearly 20 years ago. It's on its 8th mainboard generation and every part has been replaced at least 4 times, but I've never replaced the whole thing in one go so I consider it the same machine. Very Ship of Theseus situation.
I have a spreadsheet of basically every part and upgrade back to the original build.
Unrelated, I used fuzedrive with a 1tb ssd and a 3tb mechanical for a while as well. Works pretty well.
Pc, 5900x, 4080.
I love mods and can't handle a controller for anything but racing games.
