I still rem the PC-Chips SuperSocket7 mobos that used an unstable o/c standard Socket7 chipset and lied about the FSB being 100mhz when it was in fact at 95mhz using a chipset only ever design to have an 83mhz maximum. VERY NASTY.
After this I heard nothing but bad things about reliabiltiy, quality and support regarding PC-Chips. Sure they were cheap, but nasty too. The do now re-badge their mobos, ECS is a common and relatively popular solution that I'm 95% sure is a re-badged PC-Chips mobo.
However, Kurlon's right in that (certainly now-a-days) the chipset really dictates the reliability and perf of the mobo. Most people seem happy with ECS from what I've read, so if you really want to save $20 on a mobo then PC-Chips might not be such a bad thing for modern day mobos!
You should be able to identify the mobo via it's BIOS string (but it's not easy). You could try the free SiSoft Sandra Utility which should provide you with a lot of useful info including the chipset used. However the CPU Socket and speed should give you adequate information as to how upgradable the system is etc.
Best of luck.
