Antec seems to be phasing out the 900 in preparation for the Antec 1200 series. A number of hardware sites are listing the 900 as out of stock or deactivated. I have an Antec 900 and I like it, but it is a bit small and the bottom style PSU location doesn't work well with all PSUs. For what you list, though, the 900 should fit the bill nicely.
