So far the machines have been working perfectly. Our delays have been caused by vacation schedules and other pressing projects. It's just manpower, not technical issues.
So far all i can say is "WOW"! Dual core is the bomb! I'm already planning for a dual dual-core machine next! The DIY4 nachines were a pleasure to buyild and the results out of the box have been even better than we expected.
You can follow our Black or Green machine configs and you'll have a killer NLE machine!
There is probably not a day that goes by when I don't check for updates on the DYI 4 page. However, in my case it is mainly for interest since I have recently put together a system that is a near clone to your DYI 4 "Green" machine. About the only significant difference is that I put in a Raptor 10k rpm boot drive and a GeForce 6800 video card with 256Mb of RAM.
Which brings up my question: Was it a cost trade-off not putting in a high-end boot drive even in the Liquid Vaporizer? Maybe you needed to keep the boot drive consistent between the platforms for comparison purposes.
