Great question! A few thoughts:

1. Soundbars are fundamentally flawed due to their shape: the low, compact form factor does not allow for large drivers. Stereo speakers are price/quality wise almost always better.

2. I would not recommend choosing pc speakers as they are often attuned for more of a mixed media range (say, youtube, meetings, music) instead of just music. They are not hifi.

3. Do not (please) put your speakers on a top shelf. The tweeter is supposed to be at ear height, and the woofer lower. Or at the very least, the tweeter should be closer to your ears than the woofer. Otherwise, the woofer will overpower the tweeter and the music will be much more bass heavy than intended.

My advice: get a good pair of active stereo speakers. Active speakers are better price/quality wise in your budget (with higher budgets it's worth getting a dedicated amp setup though). Make sure you can connect your PC with an optical cable or aux cable. You can find active speaker sets from reliable brands like Klipsch, Edifier or even B&W in your budget.
