Still building furniture for the home office (which is currently a mess as a result).  But I'm on the last piece, a window seat (not pictured).  It's nice to have stuff designed to fit the space I need.

Workstation under the desk on the far left is a Threadripper 3960X with 256G of RAM, 5 NVMe drives and 10G ethernet.  Custom loop (CPU and old 2080ti GPU).  It's my Linux dev machine.  There's a Mac Studio with 128G of RAM that's my primary desktop, tucked under the right side of the over bridge of the left desk.  Audio gear for conferencing and a drawer racked in the shelves on top of the desks, headsets hung in the bottom nook.  Under-desk rack has two ethernet switches connected to each other with a pair of 10G fiber connections (LACP).  One of those switches has a pair of 10G fiber connections to the main switch in basement.  Under-desk rack also has a PDU with pull-out lights, a CloudPlate for front air intake and a big old UPS that just won't die (batteries replaced roughly every 3 years).  Patch panels front and rear let me keep the front cabling tidy.  There's an exhaust fan panel in the rear.

I built all of the furniture.  Wood is oak, desk feet are Delrin, desk inserts are porcelain slabs (near impossible to scratch, PEI 5).

The under-desk rack is one of the more challenging things I've designed, since there was conflict between aesthetics versus function and strength.  I think it turned out well.  The leap was 'the front door is a box', which allowed me a lot of ventilation.  It stays cool but the fans are near silent.  It can easily be rolled out to gain some work space. It's only rolled out about half way in the picture.
