I created new standoffs for the micro ATX motherboard using 3mm nuts and bolts. These were secured to the metal case using this cool metal epoxy stuff from B & Q that looks like plastic explosive.
In terms of airflow, I placed two 80mm fans in the base drawing in air from underneath and a larger 120mm fan in the top of the case blowing the warm air out. I used an unused HDD caddy from my MDD Powermac to hold the SATA drive. If I need to house more drives, they can go between the fans.
Oh, and I had another spare fan so I stuck it over the old vent holes halfway up the inside of the case. I figure this will blow air on the fanless Asus 7300GT graphics card but cannot vouch for its effectiveness.
Because of the position of the sockets on the motherboard and the distance to the PSU (bearing in mind the open and shut case), I had to extend both the 24 pin and 4 pin ATX power cables. I just used off-the-shelf cables for this, keeping the hand-crafting to a minimum!
I wasn't going to use the Zalman fanmate for the CPU fan but when I first powered it up I realised it was essential - this so-called quiet fan makes more noise than all the others put together.
I just realised - these pictures don't have the graphics card installed - oh well. I'll have to take some more.
