Haven't been able to do it, as I was busy assembling flatpack furniture. Ikea have a lot to answer for.
I shall give it a go tomorrow, as I shall be left in the house alone. Need to put the PC downstairs where it's coldest, wire all my fans up for 12v and pray to Zeus that tomorrow won't be a hot day. Then we'll see how things go

Shall be sure to post in here the results of my activities.
