Well, the wait is finally over. The beast has arrived!!!
It took about 13 working days but the delay was due to a cooler fan that they couldn't get hold of. I changed to a water cooler and it arrived very quickly after that. Very well packaged. Great communication.
I decorated the room while I waited for it to arrive. Only need to make some cupboard doors now and its done. Here's a few pics. I've included a before and after of the desk that I built. I made the whole thing from some plain wood that I bought (with a lot of help from my wife). ;-)
Would highly recommend PC Specialist. They are an excellent company. Will definitely use again.
