I'd say it was a very good experience. They were prompt and kept me posted of my order status. They were also responsive to my email.
As promised, I received a Duron processor (600 Mhz) which overclocks to 1000 Mhz and it is rock-solid at that speed.
OCZ's own brand, "Select", memory also works well, allowing 4-way interleave and "Fast" settings at 133 Mhz. Right now I am running CAS2 for testing purposes but OCZ has better memory which they endorse for CAS2 and even higher speeds (but at twice the price). Their memory is their own brand.
When I finally put my system together and closed the case I found the CPU was running at 55 degrees C. I thought this was too high so I rearranged some boards and cables inside the case for better cooling and reduced to 900 Mhz. Now the CPU doesn't reach any higher than 48 degrees. I emailed OCZ regarding my experience and they suggested that I should have removed the thermal tape from the cooler and used thermal paste instead. Installing the cooler was a little hairy so I think I will just settle for 900 Mhz. The cooler does fit the KT7 very nicely but it still seemed too easy to mash the Duron. My original intention for this system, after all, was just to have the security of knowing that I could go to 1000 Mhz. Most of the time I don't need the extra speed. And even at 600 Mhz this thing is much faster than my old K6-2, 400 Mhz.
I highly recommend OCZ.SAFESHOPPER.COM! (and they lowered the price again on the Abit KT7, Duron, Monster II Cooler combo!) I think it's now $214.99. Good price for 1000 Mhz!
