Yay! I've finally plunged and went down the WHS path. Scored a mint HP MediaSmart EX490 from Christchurch Harvey Norman Moorhouse for NZ$699 (RRP at $1149 or there-about). Norman Ross still priced theirs at $1099, and even went over to Global PC next door to price a custom built which is at $1099.)
Anyhow, this EX490 has Celeron 2.2GHz and capable of 64-bit, so hope when WHSv2 Vail is out, it is upgradable, otherwise I am just as happy with a WHS. :-D.
So what's recommended for essential WHS add-in?
