I've been looking into upgrading my Optiplex 5040 (Not quite sure of the size but it's the one that folds out when you take off the side) and I've been wondering what upgrades I could put in it. I was thinking about this:

More RAM - 16GB is already quite a bit but I want to kinda future proof myself

Higher Storage - Already have the parts ordered to put an SSD in, I just want to know if there's enough space and enough sata ports on the mobo to keep the original hard drive for games as well as keep the optical drive.

Better CPU - The i5-6500 is REALLY old and I wanted to at least put an i7 in it and possibly get a higher generation

Dedicated GPU - I've been looking at an RTX 3050 as it's nice and cheap but still part of the newest 30 series

Bigger PSU - I'd only do this if I didn't have enough wattage for to support the rest of it.

 

Can anyone tell me if these upgrades are even possible and/or where to find the parts for them? Thanks!
