Default Infamous Rubycon MFZ... Current recommended replacements???

What we have here today is an Intel DG33FB motherboard, circa 2007... I need to replace some of the caps on this board... From what I have found, one of these caps was sort of well known here back in the day as they were used in XBoxes and XBox 360s as well....They are the Rubycon MFZ series, in particular the 6.3 v 3300uf 10mm X 20mm... I have found a seller on Amazon, The Capacitor Store, that has them listed but I have a hard time believing these are genuine pieces... The original recommendation was to replace any bad ones with Nichicon HZ series since the Rubycon MFZ's were a custom product, not even a datasheet available... The HZ's have since been discontinued, what would be the current recommendation here???

Next I have a Nichicon KZG 6.3v 200uf 5mm X 10 or 12mm... Replacment???

Along with the 3300uf caps, I also need to replace a Rubycon MFZ 10v 1000uf 10mm X 12mm... Which I assume will be replaced by the same series as the 6.3v 3000uf... I have attached some pics of the motherboard showing placement of all the caps in case usage helps with choice of the replacement recommendations...

Thanks in adance for any help!!!

Default Re: Infamous Rubycon MFZ... Current recommended replacements???

I managed to buy a small quantity of Nichicon HZ 6.3v 3300uF for old jobs, but you don't need to use Nichicon HZ.

You can use something like this instead:

For the 6.3V 220uF cap (it's 6.3mm by the way, not 5mm), use this:

For 10V 1000uF, use this:
