I bought barely used M82 3395-A66 ThinkCentre with G640@2,80GHz (bios v. 9SKT97AUS) and 8GB RAM, Samsung 850 EVO (250GB) for HTPC and classic desktop purposes. Since there are confusing information regarding MBO limitations and processor type support, I would be gratefull if someone would point me in the right direction (haven't found data sheet that would explain limitations).
I plan to upgrade CPU to i7-3770 (not shure plain, K, T or S version), pump up RAM to 32GB and put another HDD inside (or few external).
Tnx in advance!

Yup, you can upgrade to the Intel i7-3770:
You can visit Lenovo parts list, and enter 3395 to see the full list: http://support.lenovo.com/us/en/partslookup

That's a plain i7-3770 only, not one with any letter behind it. (A processor that has been installed by Lenovo at some point during it's production run)
Also check the wattage of a G640 against a i7-3770, if they are different, then the i7-3770 may have an uprated cooler (heatsink and/or fan -- with different part numbers in Hardware Maintenance Manual), and you will need to change it also.

Were you able to upgrade ?
I'm looking to replace a g540 with an i3-3240.
I didn't see it in lenovos website, but i found configurations sold with such i3, doest that mean that it is going to work for me ?

I think any of the processors listed on your systems spec sheet, that are 65w or less (since your current processor is 65w), could work.
I recommend that you update to the latest BIOS using CD ISO so that has support for all these processors.

Actually since i revisited that support sheet i saw the i3-3240 in there. I updaded my BIOS to the latest one from lenovo, but i did that via the .exe file.
Is there difference between ISO and .exe updating ?

No. But ISO is more reliable, as it avoids any Windows related issues or problems.
