Many thanks to all who have in any way helped me get things to this stage.
Present setup is in my sig.
Top 140mm fan removed and mesh sealed up using cardboard, cut to size and painted with black oil paint (camera flash evident).
The left side panel given the same treatment.
Both side panels were covered with a layer of bitumen tape before speaker foam was applied. The foam already had a pre-applied layer of bitumen for extra density. The panels now have a satisfying dull thud sound to them when knocked on.
Front fan cages snipped and u-channeled. I only stabbed myself with the sharp bits once.
Rear mesh snipped and u-channeled. You can also see the Arctic F8 that replaced the stock fan in the Earthwatts 430.
The system. Egg crate foam on top and bottom of case. I'll probably go modular for the PSU with my next rig.
Close up of the Arctic 64 Pro heatsink with 92mm Nexus attached. Four silicone grommets were placed on the bungee cord behind the fan to reduce any possible vibration. Fan is attached using 3mm bungee cord.
HDD suspended using four loops of 3mm bungee cord, 4x19mm washers and spare thumbscrews ( you get loads of them with the case).
HDD suspension viewed from above.
Suspension for the backup hard drive in the 5.25 bay. The drive isn't permenently installed bcause I only backup as and when I feel necessary (normally once a month), and I don't generally add lots of of data during that time.
And finally... some temps and readings.
The fan speed for the GPU can be disregarded. For some reason the Twin Turbo acts flaky and won't give a stable reading below 50% fan speed. Also, the speedfan reading for CASE refers to the front and rear 120mm Nexus fans, as they're all on the one header. CPU, Sys and HD0 temps will all normally rise by about 3C if the room is warmer than normal, or if more windows/applications are running. At the point of time, the only thing running was my messenger program (main window, 2 webcam windows and a call to my fiancee in America). Case and CPU fans are raised to 60-65% before gaming. GPU fans stay at 41% at all times and the card has never reached 50C during gaming since the aftermarket cooler was added.
Thanks for viewing. Any comments/questions are welcome.
