NXC Capacitors seems to be from Korea. Manufactor Samyuong.

You guys left out two popular Japanese capacitor manufacturers seen on computer products, one is Nichicon with the marking nichicon on its side, and the other popular cap manufacturer would be Fujitsu Media Devices which produce Functional PolymerCapacitors (FPCAP). FPCAPs are solid caps, and the marking would be in red, with the logo being a F letter (standing for Fujitsu) with lines on the top and bottom of F.

below is from your site, the red caps seem to be FPCAPs

Another thing to note would be that there are electrolytic capacitors that at first glance look like solid caps since they have no sleeves (the colorful wraping around the cap with logos printed) on them. The same can be said for solid caps as there are solid ones with sleves on them (Yellow sleeved FPCAPs and purple sleeved OS-CONs from Sanyo would be famous).

The silver, sleeve-less caps shown on the first page seem to be normal electrolytic caps and not sollid caps....maybe FL series from Nippon chemi-con? not too sure about it though

There is also a hybird type of cap, like the EPcaps made by Sunelec (they also make these as HS-CONs for Sanyo) but this would be not that popular.

KSC should be KINGSUN ELECTRONIC

Other caps seen on mobo's and psu's
fuhjyyu: known to leak, logo resembles Hitachi
http://www.fuhjyyu.com.tw/
Asia'x: maybe subsidiary of fuhjyyu?

Ltec: Luminous Town Electric
http://www.ltec.com.tw/
Samxon: Man Yue International Holdings (also makes solid X-CON caps)
http://www.samxon.com/

As for identifing the manufacturers of solid caps without sleeves, they are too difficult since there is so little info written on them. Fujitsu ( F logo/red letters), Chemi-con (rectangle logo/light blue), Sanyo (purple, thin letter font), Cushy (FPCON, 8 inside circle logo/purple), APAQ (AP-CON, dot inside C logo/purple), Elite (S inside C logo/purple) seem to be the few that are noticable.
