Using a power strip in an old home that was build back in 1955

I'm not an electrician, but this sounds like living dangerously to me. I think that it's illegal in my jurisdiction to have a three-hole receptacle which isn't grounded. In any case, I would never do it because that ground pin can save your life.

Also, most surge suppressors route excess energy into that ground pin. IF that's connected to nothing, then protection is nil. The first thing I did when I moved into a 1950's house was upgrade all the important circuits to 3-conductor, along with a 200A service.

Just my $.02 - but I strongly urge you to consult an electrician.

I may be living dangerously, but nothing bad has ever happened. I've never had a fire start or anything. Maybe I'm just really lucky.

Your circuit, which likely consists of several to many wall outlets, is likely on a 15amp breaker, if you have breakers.   This can be easily overpowered with that number of outlets on one strip.  Add up the amps of each thing you intend to plug in.

22 is too many things and noisy to boot.

I agree 15 amps is not a whole lot for high end systems.  Better to feed your rack from more than one circuit, if possible.

I wanted to have a third pin actually grounded where the outlet's third pin was not connected.  Got an electrician who ran a wire to a water pipe in the basement.

My home was built in 54’. If you have conduit, have an electrician pull all new wire and grounded outlets. Mind you, the outlets must be to a grounded panel as well. 
I would do this if money allows. Should be about 5k.
