It really depends on what you want to do. Word processing it can handle, scientific analysis it’ll be slow at, 3d modelling it’ll end up in power point mode quicker than newer machines. Coding would be fine, though compiling would take longer and testing may or may not be viable.
A reasonable desktop from that era should be about comparable to a Raspberry Pi 4, which can certainly be useful. Power consumption is probably the main argument against it.
If you actually tried to do anything useful on a 2004 machine, you wouldn’t post that.
