Cocktail computer\retrogaming station

[nivlat]

Hello all,

I'm planning on building a cocktail style computer/retrogaming.
Essentialy it will be a table with a 22" monitor lying flat in the center, all covered by plexiglass o tempered glass, with a raspberry, speakers and all wiring hidden inside the table.
I'm aiming to use it as a pc for internet browsing with a wireless keyboard and to run retropie with with wireless joypads.

Few questions for the more savvy.
- I read somewhere that monitors are optimized so that you can view them clearly from above, but not from below, so I thought to mount it "facing away" from the user and to rotate image 180 degrees. Is there a way to set both the raspberry OS and retropie to automatically rotate screen 180 on start up?
- On the same topic, since the user will be looking at the screen from an angle, is there a preferred tecnology? led, lcd, etc...?
- Would there be a problem plugging 3 wireless devices on the Pi? keyboard and two joypads

Thanks!
