Have a look at click here, my son buys from here for his business and is very happy with products and I have bought a motherboard bundle from click here and am happy with the machine I built. The advantage of a bundle is that the processor and mobo are built and tested so that removes doubt from the equation. As well as that the value for money was better than bundles offered by larger firms
You will have to check the spec of the case to see which size mobo it will take, I have Antec Solo Quiet Mini Tower Case - Piano Black/Silver - No PSU which is very good quality and very quiet with a Trust 'Pro PSU Low Noise Big Fan' 520W PSU. I fitted a Freezer 7 Pro processor cooler and I only hear noise from the fans at start up or if I am doing a lot of processing (like doing a virus scan)
Thanks very much for that, I'll look into it! And once its all come through, is it very much a case of just literally putting everything together and then turning it on with windows ultiamte in the disk drive?
