CentOS Compatibility with HP EliteDesk 800 G1

[Ajt_Cova]

Dear community,

I have my eyes set on a HP EliteDesk 800 G1 to fulfill a certain need I have, for which I need to set up a machine with CentOS 7 (specifically). Why a HP EliteDesk 800 G1? It's price and availability in the market I find myself in right now (low tier developing country).

My question is: Are these HP EliteDesk 800 G1 desktop computers, which usually come with a 4th gen Intel processor w/4-8Gb of DDR3 RAM, compatible with CentOS 7? In case they are, is there any difference in compatibility between the i3, i5, or i7 models with 4 or 8 Gb of RAM? And in case no model is compatible, which specs should I be looking for? or which similar, compatible, models are there? (in hopes they're available where I am located).

Thank you very much for you time, 

Kind regards, 

Ajt_Cova

I believe you will be OK, but there is one thing to take into consideration.  We have not run CentOS7 (that i recall), but have successfully run the Fedora based QubesOS on these with the i7 CPU. We also run PopOS, LinuxMint 18, 19, 20, and 21. The biggest catch has been a hard crash of the monitor and or backlight or Driver that kills X and often all the TTYs.   From another machine, one can successfully ssh back to the seemingly dead machine, but usually a reboot is required for the console to be usable again.  Killing Xorg may work, but when all the CTRL-ALT+F1 through CTRL-ALT+F8 ttys are dead as well, sudo reboot from ssh seems to be the only option. Otherwise, a hard power reset or MeshCentral vPro remote power reset.  If there was a way to reset power to just the LVDS screen in the All-in-One😕, then this would not be an issue. 

A workaround is to disable the ScreenSaver and PowerManagement for all users and especially the initial welcome / logon screen as detailed in <SOLVED> Disable Screen Power Management for Logon Screen?

Lack of conformity to the Extended Display Identification Data or EDID is a likely culprit. You see the BIOS will list three models of internal LVDS monitors, but will always revert to Auto Selecting the internal monitor. That alone makes it hard to troubleshoot.   There is a likely solution in either rewriting the edid or educating the driver developers.   I will post the edid-decode output in a separate reply.
