I finally decided on an assembled machine

After much toiling and deliberating, I elected to buy a ready built machine.
It was a hard choice as I kind of fancied the challenge but I priced it up several times and it was only marginally over £50 more for the ready built machine from a PCPRO A-list company over a self build with all of the associated issues.
They will deliver before Xmas so, a nice present to myself!
