Mac mini M2 (2023) An M2 Mac mini - I think I have the Apple (non)capitalizations correct - was too good to resist. "Only" an M2 chip rather than an M2 Pro in this one, but that is plenty fast enough for me. Apple finally made the baseline memory more than 8Gb on the newer, smaller 2024 Mac minis - but not this one.
RPi 5 The latest and geatest ARM chip without the keyboard (or anything else). Raspberry Pi OS still helpfully contains a free up-to-date copy of Mathematica and Raspberry Pi OS 64bit speeds things up a little bit. A 16Gb RAM version has just been added to the roster.
RPi 400 An ARM chip inside a glorified keyboard connected up to everything else via lots of wires for less than a hundred quid - is this 1980? Odd that the mouse appears to be set up for left-handers.
RPi 500 It took a while, but they finally transplanted most of the RPi5 innards into an RPi400 style keyboard. The USB ports have migrated to the correct side for right-handers now. There isn't an NVMe connector on the board, unlike the free standing RPi 5 board, which has annoyed some. There are no complaints from me, it is still fast and cheap.
