Mini-PC spec -- advice please

[colevalleygirl]

I'm looking to buy a mini-PC (mini because the space available for it is limited).

Intended use: Internet, Access programming and running big Access databases, word processing, large Excel spreadsheets, some basic photo-manipulation, Skype video-calls.

I'd like it to be as quiet as possible and as low power consumption as possible (but the right performance is more important). Any comments on the spec below -- in particular, have I gone over the top with anything and where if anywhere could I pare it back?

Proposed spec:

Processor (CPU)
Intel® Core™i5-660 Dual Core (3.33GHz, 4MB Cache) + HD Graphics + Turbo Boost
Motherboard
INTEL® DH57JG: H57 Express Chipset, 10-Channel HD Audio, 2x DDR3

Great spec - are you sure you need W7 Professional though? Compare the editions here: http://windows.microsoft.com/en-US/windows7/products/compare

Pro will let me backup to my NAS, so the question is whether I can get a reliable backup programme for less than the incremental cost (£30).
