Blimey. I was looking at spending a similar amount to use an old Winchester S939 Athlon 64 I have kicking around here.
That first spec looks great for a boggo email/'tinternet machine - only problem I can see is the crappy intel IGP which would be rubbish for video - anything more than 720p would make it wet itself I imagine.
Shame there is a distinct lack of shuttle/barebone MiniITX boxes at that price range with PCI-E - one of those, 2Gb RAM, cheapy HD capable GPU and a cheap HD connected up to a NAS would make a perfect all round PC for when I don't want to boot up the Big Box.
Unless anyone can suggest a MiniITX setup with PCI-E. Or something I can do with this Winchester I have here....
