Built my first cube (a powered 630) in late 2010 and maintained it until early 2016. Built a copy of The Pauper Cube at the end of 2018 and after a few years of it sitting dormant without play I decided to retire it in Early 2023. Keeping the list here in case I want to revisit it some day.
I'd been toying with an Old Frame cube since I got in to Old School and TSR pushed me over the edge. That cube is now my primary focus.
Then I decided I wanted that powerful feeling again and rebuilt my powered cube from the ground up to round out the levels of cube experience I can have.
