Help finding motherboard model? (Lenovo H330)

[ksbd]

So, I've been looking all over the web for some reference to my computers motherboard, but can't find it. I've stumbled across Chinese parts list for every Lenovo product, which basically said N/A when it came to the motherboard for my model, I've tried searching the Lenovo site to no avail, posted in their forums, looked at the manual, etc.

Basically, I'm wanting to upgrade my computer to optimize gaming on a budget. I need to get a new casing because this one is too small, probably a new power supply, a new graphics card, etc. The thing stopping me is the lack of documentation.

I've opened up my comp as far as I dare, so here are some pictures:

Any help would greatly be appreciated.
There was also a serial tag I couldn't get a picture of. It was located under the fan, with the serial; "EA = 4437E641DF71".

Off topic, if anyone has any suggestions for a new case, power supply or graphics card that isn't gonna cost me over £600 all together, throw them in as well if you'd like!

Thank you for anyone who took the time to read this, even more so for any replies.

ADDITIONAL: CPUID says "To be filled by O.E.M", so that doesn't seem to be of any use to me...

I never did find the manual, if it's out there somewhere, then good luck trying to find it... Also, I'd seriously suggest swapping the CIH61C out for a new board, it gave me no end of troubles after the warranty expired.

Sorry I couldn't be of help mate.
