There's a difference between appreciating the review and the looks of the case. I do appreciate your work, it's just that the case hurts my eyes.

Does this material have good thermal conductivity, both as a solid and as a liquid? Would the capillary forces really prevent it from leaking when it melts (and surely it will melt several times every day)? If it leaks, it almost certainly will short circuit something on the mobo. Does it react with...

Power consumption differences between different brands of the same GPU are a big problem - it might be that there is a much less consuming 5750 from another brand and that the 5850 reviewed was on the low side.

I was a bit surprised of how much power an optical drive needs. I suppose it's the laser there which is hungry. I doubt it. Probably rather needing to move a heavy read/write head around and spin a far from perfectly balanced heavy disk. Hard drives have much lighter read/write heads that have shor...

My guess is that you made a duct from the exhaust vents to air exhaust vent of the room.

I have planned this myself more or less seriously, as our building has fully forced air circulation.

1000W with 80% PSU = 200W for the birds. That makes a whole kW/game (5h)!! If the PC idles the rest of the day at 70W (19h) and energy efficiency is only 60% at that level, that's another half of a kW for birds. Well, maybe birds save their energy since they don't need to fly far to south at winter...

Case fans. System is a bit too hot for the closet so case fans are running on full speed. Still the door blocks most of the noise so doesn't matter much.

Air vents for the forced air circulation in this building make the most noise.

I believed that the PFC on PSUs were designed to correct the AC power factor that is delivered to your house.
