The memory spec is the same, thanks mm, and no extras are included; just motherboard, memory, and CPU. I don't doubt the quality of after sales service if the truly excellent sales service is anything to go by, but for sixty quid less including VAT and P&P, I get 8GB memory instead of 4GB (same spec), the i5-3570K overclocked to a reliable 4.4Ghz instead of i5-3550 delivered in standard 3.3Ghz trim and not designed for overclocking anyway, and a decent CPU cooler (none incuded from DVC).
After sleeping on it I have made a small change and decided to pay the £20 premium to stick with ASUS as the mobo supplier; I much like their products and have never had one fail. I like their implementation of UEFI BIOS, too.
is what I have now ordered.
Happy to report back the outcome (including how I get on with MS!) if any fellow PPRuNer is interested. This will be some weeks if I don't manage to get to installing and configuring before I disappear on holiday in the wee small hours of 19th July.
Thanks again for all the help and advice; as always, appreciated.
