HVAC Guys: What is this and how bad is it??

[HoneyBadger]

Woke up this morning and noticed the furnace had water all around it. When I saw it, there was about 20oz of water on the floor. I'm not sure if any of it or how much actually went down the drain, but apparently my builder did a crappy job of sloping the floor to drain water here.
Here's what I know:
-The water is definitely coming from the furnace (not the hot water heater).
-The humidifier is dry as a bone (only runs when heat is on, heat hasn't been on in months).
-It's not coming from the intake/exhaust pipes.
-Nothing elevated off the floor is wet. None of the inside or outside walls of the furnace are wet (as far as I can tell).
-It rained a decent amount last night, but nothing more than we have been getting any other day here lately.
-It is definitely water.
-The source of the water doesn't seem to still be leaking/draining/pissing.

Pics: (If there are more helpful pics I could take, please let me know and I'll go take them)

The original water line didn't cross the blue tape lines. There were some things there that I had to drag out of the way.
