Actually I really like the Era ITX (maybe I should have written "no bling" as opposed "not fancy" - original post updated to reflect this), but unfortunately it's just a tiny bit too small for the graphics card (like the other options). I've realised there are quite a few SFF cases with support for ATX power supplies, however, so that opens up my options quite a bit.
The Silverstone GD09 seems like a good compromise for an ATX build, although I'd position it vertically.
Edit
Just came across this SFF spreadsheet - some of it is quite outdated, but might be useful.
