Shuttle SN21G5 a good choice?

[uk_sam]

I'm planning to build a shuttle system for a friend and the SN21G5 seems to be the cheapest one (£210) to support an AMD x2 3800+. I plan to pair this with a x1800xt but I'm a bit concerned about the heat generated and also whether the 250w PSU will support it. Is the SN21G5 a good choice and should i get a slightly lower power graphic card like the 7600GT or the x1800gto?

Thx bbreezeuk. A more powerful PSU would be nice although I've heard that the 240w Shuttle PSU are fairly good for their power rating. I managed to pick up the ST20G5 for £180 which suits me as I am on a very tight budget and those Shuttles are not cheap. Were money no object I would definitely go for sn25p.
