    I want to know if I add a new node that is on a newer dell 620 server with Win 2008r2 into an existing SQL 2005 two nodes cluster on old dell R900 server with Win 2003 OS; would work. My assumption is that I will have to have identical hardware, OS. Please advise.

    You need to have an identitical OS as clustering changed quite a bit between Windows 2003 and 2008. You also cannot upgrade the existing cluster to 2008, it would need to be completely rebuilt.

    In 2003 you needed Microsoft certified hardware but in 2008 it just needs to pass the cluster validation tests so hardware does not need to be identical.
