Abram, nice aesthetic choice.
Regarding VGA sides, I mostly agree with MobsterOO7. VGA sides in PLP looks perfectly acceptable. Sides of PLP can be of slightly inferior quality to center, & it makes minimal difference because you stare at center. You don't notice minor imperfections on sides.
VGA sides still look fine for surfing & Word, but you wouldn't do precision art on VGA sides. You do it on center like normal.
VGA is slightly lower visual quality & will have more tearing in games. So depends how perfectionist the gamer is, price requirements, monitors on hand.
VGA also has a strength: it is about the most forgiving connection available. If all else fails, VGA likely works.
Here's details for your chosen layout.

your side bezel size does not matter very much, as they will be hidden.
EDIT:
You can find some other 19" examples here. I don't remember which of them are best.
