There is quite a list there, from old used PC's to some new builds i did (one or two costing more than 1K$) and also somewhere there is a reason why a list can not be made, namely an Acer laptop that worked perfectly for machine control with no issues for weeks at a time, so i got another one, same model, same numbers, same look, same everything = it was useless, utterly useless. The processor was not the same stepping/family/model.
In general, Enterprise Edition PC's from Dell, HP, later Lenovo, and especially Fujitsu, work and chances of it working for LinuxCNC are as follows:
Fujitsu = never had one with bad latency, out of about 20
HP = about 1 in 15 might not have good latency, even then can be fixed just by removing the add on graphic card
Lenovo = 1 in 7 might be bad latency and not easily fixable, rarely have BIOS clock issues ... complicated
Dell = mixed bag, you can go through 20 and all will work then end with 10 that do not, always, always between generations (not processor generations)
The works/does not work above refers to LinuxCNC, not the actual PC, they all work and are very, very good hardware quality vise.

The point of the Wiki is that anyone can update it.
If you think it is out of date, then consider fixing it (it sounds like you are already collating the information)

You might need to follow the "BAsic Steps" link above to see the edit link. And then you might need to know that our penguin is called Chips. 
 

Whatever happens it should be good to include this topic by MozMCK on improving latency, he did a great job of figuring out what should be changed and also made a script that fixes stuff automatically, seems to make a huge difference for almost any PC.
