Need help identifying these "polymer" caps

[Travis]

See attachment below. This type of capacitor used to appear on MSI's LGA775 motherboards. The motherboard taken as an example is P31 Neo-F and you can see them in CPU's VRM output stage:

Sometimes they're replaced by OST's RLA series (in blue sleeve) electrolytics so I suspect they aren't polymers?

It's also interesting to see that MSI used Japanese capacitors in the "non-critical" areas of this inexpensive motherboard, like:

PCI power filtering and chipset power

Memory power

So they're somewhat better than these Japanese counterparts?

Those are not polymer... PCBONEZ was kind to inform me that those are Panasonic FL... The "vent" is a plug in the bung, on the underside of the cap...
