How would a Minecraft server run on these 2 PC's?

I have two PC's that are sitting in the basement doing nothing, they both work very well considering their age.
Specs-
The custom Dell PC has an Intel Celeron Processor, 465 MHz, 512 MB of RAM, running Windows XP 2002 Service Pack 3. The Ultra PC has an Intel Pentium II Processor, 350 MHz, an absolutely stunning 144 MB of RAM, running Windows XP 2002 Service Pack 3 as well.
So what I was wondering was if either of both of these computers could handle hosting a 1.10.2 minecraft server for 4-10 people (4 people is the absolute minimum). What would the lag be like? Would it be block lag (having to break a block multiple times) or frame rate lag?
I just want to know if this would be possible and if it is, what the condition of this hypothetical server would be. Thanks!
P.S. Also, and this is a stretch, I know, but would this server be able to handle about 5 Forge mods?

Can you run a Minecraft server on multiple computers?
No, this is not possible. Due to the way Minecraft, Bukkit and Spigot are coded, you cannot run the same instance of a server on two machines. Minecraft worlds are locked to one instance at a time, and that instances of the software cannot share data (plus it's inefficient anyway).How do I run a Minecraft server on another computer?
