Building a quiet Shuttle any advice?

[JezHancock]

Hi this is my first post so bare with me.

I would like to build a reasonably quiet Shuttle or similar SFF for my living room.
I have a budget of a max. £1000 for the computer itself. The peripherals and screen will be bought separately from this budget.

I was proposing to go for these componants:- Shuttle XPC SN25P, AMD Althlon 64 X2 4400+, Corsair 1GB DDR XMS3200C2PT TwinX Cas2, HIS Ati Radeon X1900XT ICEQ, Samsung Spinpoint P SP2504C 250GB, Pioneer DVR-111BK 16x16 DVD+-RW, Askasa SATA-2 45cm Silver data cable, Askasa "Y" power splitter, Askasa PCI express 6 pin to 4 pin power cable adapter and a copy of Windows XP Home Edition. All of which I priced up today from Ocuk to £910.16.

I would be paring this with either a Belinea 20.1" or Dell UltraSharp 2007WFP 20" widescreen LCD monitor hence the need for a fairly powerful Graphics card.

Any suggestions, advice and possible alternatives would be greatfully received.

Ok I've been tempted down the route of building a Apevia (Aspire) X-Qpack.
This will mean I can go for a Conroe CPU using a Asus P5B-VM micro-ATX Mother Board.
I'd like to know if a HIS Ati Radeon X1950 Pro ICE-Q 512MB will fit inside? I realise that I would lose the use of one PCI slot.
I would likely use a Sharkoon 120mm silent Eagle 1000 to replace the case fan. This would hopefully cut down noise as the LED 120mm case fan supplied with the X-qpack is a little noisy.
I would also like to know if there is a low profile HSF that is cooler and quieter than the Intel reference design? I understand that there is not enough headroom for the likes of the Arctic Cooling Freezer 7.
Any thoughts & advice?
thanks
