What stuff do you like besides CPUs?

rowing medals, 1950s and older as much as possible.

I've got a strange collection of hobbies I guess.

-CPU's obviously, but GPU's as well.
(Honestly my favorite thing about PC's is overclocking and modifying systems to do things outside of spec.)
-Cooling Systems, everything from making custom heat sinks to custom water cooling loops, LN2, Chilled Water, Cascade Phase Change, TEC's, etc.
-Cryptocurrency mining (Started back in ~2011). Although I don't near as much anymore as the community became very toxic and more about money and less enthusiast.
-Laptops (See CPU/GPU/Overclocking, but more difficult to portability and space constraints). High end stuff.
-Started looking into Magic The Gathering. Not into the card game for playing purposes, over the last ~10 years the value of these cards has gone THROUGH the roof. Maybe a fun way to invest and collect something long term. Lots of mystery and speculation there, like Bitcoin but years ago before the bubble.
-Thermography, I have FLIR thermal imaging equipment. Purely a hobby, but it factors into the cooling and overclocking. Plus looking at the world through infrared thermal radiation is pretty incredible.
-I like playing with money too, stocks, swaps, etc.
-In the future i'd like to learn machining and other shop equipment. Gunsmithing looks pretty fun.

Really like anything that forces me to be creative and develop out of the box solutions.
