Where can I buy in the UK?

[Manxman55]

I am trying to find a GA-880GA-UD3H (rev. 3.1) or, failing that, a GA-880GM-UD2H (rev.1.5) or as a last resort, a GA-MA770T-UD3P (rev. 3.1).  I have spent an inordinate amount of time on this and cannot find them.  Where can I buy them in the UK?

The models you mentioned are discontinued models that are no longer manufactured. You might want to try the used marketplace. I see four used GA-880GM-UD2H models on eBay UK. You will need to check closer for the Revision numbers.
