I did it that way for a few reasons:
1) It was at a better eye level for me when I'm sitting down. (It will be used for things other than arcade games).
2) That way the bezel wouldn't have to have a bottom, the screen itself would be the bottom. My monitor's bottom is shapped rather oddly, and it would be difficult to cut.
It does look a little low, but I think once the whole bezel is painted black it will blend in a little more with the monitor and not look so odd.
I appreciate the input, it's always good to get some feedback.
