Hi there, I am currently in the middle of upgrading my HTPC ... I have had a Coolermaster cavalier case in my garage for a Year now which was left over from a job ... the build is complete and now have found the MACRON 300w power supply is DEAD :) YAY ... the problem I face is Coolermaster have used a proprietry power supply .... which they mount sideways ... all the dimensions are the same as a standard ATX except the width which is a low profile 120mm instead of the standard 140mm, My question is has anyone here modded there Cavalier case or managed to source locally a MACRON replacement. I will be going to my suppliers in the next few days to see if I can get a replacement ... however running 2 TERRA drives a qaud core and planning on setting up for freeview im a bit concerned anything less than 350w could be a struggle ... it seems they don't make any replacement PSU larger than 350w. Any feed back appreciated. Here is a run down of the box. http://www.modthebox.com/review356_1.shtml
