Are refurbished computer towers worth it?

I'm curious, are refurbished computer towers truly worth considering as an option for my technology needs? Are they reliable, or am I better off investing in a brand new system? And if refurbished towers are indeed a viable choice, what should I look for to ensure I'm getting a quality product? Will I experience any limitations or drawbacks in comparison to a brand new model? It's important for me to make an informed decision, so I'm eager to hear your thoughts on the matter.
