Don't worry about that. I don't know why they do that but it looks like the same glue that is holding the giant capacitor in place under the heat sink on the other end.
Most of the damaged capacitors I have found are under the heat sink closest to the main board connector.. It is very hard to visually inspect them without taking it apart and a visual inspection alone might not be enough.
There is a way to use a old PC ATX power supply to power up a Fireball but you have to modify it slightly to work. If you notice, a 20 pin ATX power supply mother board connector is identical to the Escient main board connector right down to the wire colors. To use the ATX supply as a tester, you must first snip off ALL the unused wires to make it match the escient connector. Then you have to short the green wire you snipped off to any black wire on the ATX power supply. This will force the power supply to power up full time when it's plugged in and the supply switch is turned on.
Bench test the ATX to be sure you do in fact have all the correct voltages required for the Escient to work (3.3, 5.0 and 12.0 vdc) They will read a bit high on the bench with no load in it but that's OK. If all is well, plug it into the Escient but before you attempt to power it up, run a temp ground wire from the case of the power supply to the chassis of the Escient and let-er rip.
If the Fireball completes it's boot up, you need to repair or replace the original supply. Have at it.
