Let me tell you, the FT02 is nearly perfect for high end multi-GPU supercomputing. I have two of them next to my desk right now, with 3 GTX480 and 3 GTX295s. What would make the FT02 even better? The 8 PCIE expansion slots needed for quad-GPU mounting like the RV02 has.. the FT02 only has 7 slots so...

And advanced PSUs with built in monitoring?

This may be a niche market, but I'd love to have a PSU that (like a UPS) had a USB connection allowing the PC to monitor the current power state of the PSU. This might help find situations where input voltage is sagging and (like a UPS software alarm) you want to shut down. More advanced features mi...

What's the point of using silicon vibration isolation grommets to mount an SSD? Hard mounting with raw screws is easier.

I suppose the answer is that it's useful for 2.5 inch laptop drives, not SSDs.

Intel 980x stock tower heatsink and gummy compound

My new 980x is working well. It's notable that the 980x comes with a "Real" heatsink.. a quite nicely engineered tower. I didn't use it (I use a Nocua NH-D14) but it really is a change.

But what's a 4 pin fan? And are there 3pin -> 4 pin converters?

Actually, you're lucky. Condensation is NOT a problem if the computer is on. A computer, even a low power one, is considerably hotter than the ambient temperature, and the most sensitive electronics tend to be the hottest. This will completely prevent condensation, even in pretty heavy shower fog. B...

teejay is correct. The PSU has a good 1"+ gap both above and below the PSU. There's plenty of room for air to come into the PSU's bottom fan. Also, there are rear intake holes, but, like the P180''s review shows, you can boost hard drive cooling by closing the holes, and the PSU fan will make a hard...

Nice pics!

You can reduce noise just a fraction AND increase airflow by using some tinsnips, a nibbler, or even wire cutters and removing the exhaust fan's hexagonal mesh grill. That grill isn't too restrictive, but the clearer the airflow, the better.
