As to your question, you can do whatever you want to your stuff.
I wish to use a VESA stand to hold a DELL ST2220m monitor. Naturally, the monitor doesn't have VESA holes on the back. Can I remove the Dell symbol on back and either drill into it or glue a 5x5 piece of 1/2" board to it and then drill the wood? Prefer not to spend $40 for bracket on eBay.
