When running a Mac mini server, many people see quickly that the more RAM the better. To have Apple install the RAM can be quite expensive, but you’ll know it was done right and is covered in the future.
However, if you want to try it yourself, it is much cheaper and not too difficult.
It’s hard to get a hard answer on whether this will avoid your warranty. However, in my experience, Apple will continue to cover your machine but NOT the RAM and NOT anything that may have been damaged while you installed your RAM.
To sum it up, be careful when you install and keep your old RAM in case you need to send your machine to Apple and you need to get back to stock.
