thanks for your help bedstorfromAP,
I thought that Eclipse got a good spec by putting in high spec components but then something has to give eg build quality? I guess a good spec computer is no good if it doesn't actually work!?
I had thought of Dell, I know you said its poss to get a similar build for cheaper but their PCs do seem really cheap. I wouldn't need a good graphics card as I'm not gaming or using vids much, mainly just internet, Office and also some data analysis of large data sets so may need a high RAM.
I will look at pcspecialist, I've heard of them and maybe also cougar who get a lot of good press on the PC Advisor site, so much so it seems suspicious !
