I want to do a full recap for this motherboard, especially since the previous owner had already done couple of questionable cap-swaps. I mean look at this, very shoddy! Instead of properly mounting them, he/she just cut of the legs and soldered new caps on them:

The caps he/she used are 2000 uF 10V and 100 uF 35 V. The thing is, I think the real values should be 2200 uF 6.3 V and 100 uF 25 V. However, I can´t be certain so I´m asking if someone here has this motherboard and could check these two caps circled in the picture?

2000µF is a very(!) uncommon value today. You can be sure this was 2200µF. If you find a 2200µF/10V low ESR type from one of the Tier 1 brands (Rubycon, Panasonic, Nichicon, Nippon Chemicon) - with the same form factor (=diameter and pitch), you should use it instead of a 6.3V model.
As for the 100µF you should go for quality also (not something like this "G-Luxon". 25V will be perfect, but 35V won´t hurt unless it gives you worse electrical values (ESR/impedance/ lifetime@105°) .
But wait until someone here confirms the actual values

Sorry about that, bit of a typo there: the capacitor in question indeed IS 2200 uF & 10 V. I still haven´t found confirmation about this. Anyone?

Thank you so much, this is very helpful! Now I know what to order, I really don´t feel comfortable using anything else than caps with original values.
