I bought my personal office workstation which I used for the past 4 years.
It was a Lenovo M82 ThinkCentre small form factor desktop with Corei5 procie,
4GB of RAM and 500GB of storage.

I customized it for gaming-- I bought a mid-tower casing, increased its
RAM to 12GB, installed my old psu (Thermaltake 530W) and gpu (GTS 450),
and add 2 more 120 cm fans for cooling. I also bought online a cable adapter
to connect the standard 24-pin psu plug to its 14-pin mobo plug since
it had a 240W psu only.

It all run smoothly for the past 2 weeks, but yesterday while just
surfing the net my setup just abruptly shutdown with a small bang.
Upon checking its parts, there were no burnt parts nor smell therein.
I have not used it for a day for now thinking it might bring more
damage to the mobo and other components. Do you think that the incident
just fried the mobo?

Please advise me. Thank you.

your PSU? did you check, the bang may be a blown transformator which could short motherboard. I'm guessing its re-branded pegatron viking motherboard.
