I always thought PC+Wood enclosure = Fire hazard.
Nah, In order for wood to catch fire, it needs to be in intimate contact with something that is very hot. For instant fire (like throwing a log on hot coals to continue a fire) you need to be in the ~700°F (~375°C) range.
If you are in the 450°F-500°F (~230°C-260°C) range the wood
might catch fire after a few hours of contact.
There have been recorded cases of wood gradually catching fire after being in contact with steam pipes in the 250°F-300°F (120°C-150°C) range, but this is after years if not decades of exposure. This is very rare, and the mechanism through which it happens is not well understood, but we are talking about needing at least several years of direct contact.
Firstly, the wood in a PC case is not in direct contact with any of the hot components, and secondly the components are not going to wind up being anywhere near the required temperatures to ignite wood, even if they were.
Lets a assume a fan dies on a heatsink. It's going to start rising in temperature rather quickly. Once the core hits its throttle temperatures, in he high 90's close to 100°C though, the PC is going to throttle them back so they generate less heat. The metal of heatsink itself will probably never reach temperatures above 70-80C, and even as it toes, it won't be in direct contact with the wood.
The one risk is if you have a failed power connector. These have been known to melt or catch fire if there is damage or poor design resultin in thinner conductors than specified, through resistive heating or arcing. To be fair though, these are going to be a concern regardless of the materials you have in your case, and are probably not going to be close enough to the wood for it to catch either.
Many plastics are also prone to catching fire. ABS has an ignition temperature of 350°C, High Density Polyethylene (HDPE) about 340°C, etc. etc.
When used in consumer products many plastics are treated with flame retardant additives to reduce the likelihood of them catching fire. Flame retardant wood treatments also exist. I'm not familiar with what wood Corsair has used, but I wouldn't be surprised if in consumer products many woods also have flame retardant treatments.
Depending on your jurisdiction protecting consumer products against catching fire may even be a regulatory requirement.
Anyway, this is just the very long winded way of saying I don't think having a wood panel in your case catch fire is a big problem to worry about.
