Question Help with HP EliteDesk 705 G4 DM upgrades

[CrisR82]

I just scored a fantastic deal on one of these little guys ($100!), however the exact model I got seems to have a few quirks I would like to sort out and was wondering if someone can give any feedback before I pull the trigger.

The model I got comes with the Ryzen 5 Pro 2400GE, 16GB DRR4@2666 single dual-rank stick and a TeamGroup CX2 Classic SATA SSD (brand new!).
What I would like to in the near future and the relevant questions for it:

• Upgrade the RAM to dual-channel - should I just source any 'ol DDR4 dual-rank 16GB stick, or are these PCs OEM-parts-only?
• Add a WiFi card (has a slot for it and pre-run antennas) - I see that the manual lists compatibility with Intel 8265, 7265, 3168 and 9560 - shall I assume those are the safe-to-pick options without risking it not working? (so far aiming for the 9560)

And in the distant future:

• Add a proper m.2 SSD - any recommendations for one for this class of PC? I actually have a spare Samsung 980, but that seems like a bit of an overkill.

I plan to use this little guy for Batocera and probably Linux Mint to stream games from my actual desktop PC to the bedroom, or to carry around with me while traveling as a casual-work device.

Try to find another identical model ram stick to what it has right now, even if you have to buy used that's your best bet for compatibility. It most likely doesn't have a restriction and will run non HP RAM, but mixing different sticks of ram can sometimes lead to unpredictable results. You also won't get XMP support, so adding faster ram will not yield more performance.

HP commonly enforces whitelists with wireless cards. You could research and see if anyone has run into this with your machine, but I would stick with the ones that it could have had from the factory since those are most likely to work.

Silicon Power UD90s are good budget NVME SSDs, Team Group MP33s are also another good option. The 980 is an excellent drive, despite the cache situation, but a cheaper drive is probably a better fit for a $100 PC. Although, I'm not sure your system really needs an M.2 drive, SATA drives are fine for most people, even budget ones like the CX2
