I’ve got a few upgrades that I’m looking to do to my homelab and am looking for some suggestions on what to approach first.

I’ve currently got the following mini pcs:

• 2x HP ProDesk 400 G4 i5-8500t, 32gb ddr4)
• 2x HP EliteDesk 800 G3 (i5-7500t, 32gb DDR4)

I’m looking to upgrade these units to 64gb ddr4 as I recently discovered that HP claims only 32gb supported but found there are people running 64gb in these. So that’s what I’d like to move to as well.

Additionally, I don’t use the WiFi cards in these, I run everything hardwired. I have seen some folks changing to a 2.5gb Ethernet adapter that uses the WiFi slot since the flexio port doesn’t support Ethernet in these generations. What adapters are supported?
