Hi again everyone since having the new motherboard fitted to my Dell XPS 720 it has been running better than ever and I am very pleased with it I have found on eBay an XPS 720H2C cooling system and I would like to know if it is an easy job to fit to my ordinary XPS 720 I realise the best place to ask would be the Dell community forum but I have been trying to join for the last 6 months and I have no idea of what I am doing wrong but I fall at the last post it just tells me the my names have been accepted and the account is pending so I will probably die of old age before that happens anyway I digress what I need to know is it a simple job an idiot like myself could handle or if that is not known please offer advice on joining the dell community forum many thanks Chris
