Here is my worst "Why did I ever build this?" project:

A super fast hi-Z experimenter's kit for my HP-3577A network analyzer. 
King size, LH0063 buffers and the whole nine yards. Painted fire-engine 
red (same paint I used for my 1st car), big double-shoe-box sized linear 
power supply. It worked great and I still have it.

That was at the beginning of my first self-employed foray, to be able to 
design and test baseband sections for Pulsed-Doppler. Turns out all my 
initial med tech projects later were imaging projects so this 
painstakingly built box never saw meaningful service. I did one small RF 
experiment with that and promptly blew one of the four LH0063 by 
accidentally transmitting 100W shortwave into it.

I couldn't bring myself to do it yet but some day I'll just have cut it 
loose. As we get older my wife's mantra has become "Just get rid of it!" :-)
