Obviously, there's a trade-off - but I don't see a reason why, as is your experience, in a particular room/system flattening of frequency response wouldn't outweigh the "impurities" introduced.However, it's entirely separate issue from having an optimized, dedicated to audio playback computer. It potentially introduces higher (not by much, I'd bet) requirements for processing power and memory, nothing else.

Actually the room EQ raises the processing anti quite a bit as a function of the sampling rate. Not such a problem when running PCM up to 192/24, but doing the room EQ at DSD sampling rates (without down sampling) uses major amounts of processing power and makes it essential that the computer is completely dedicated to audio otherwise there will be glitches. (This is because I have a second generation core i5. With a faster processor this might not be such a problem.) Again, the tradeoff is is between (1) no room EQ, (2) downsampling to 352.8 for room EQ, and (3) doing room EQ at 2822.4. The latter sounds best if it's a cool day, but not on a hot summer day because I have yet to solve the CPU fan problem, where the RPMs reach audible levels on hot conditions.

Have you tried a high performance heatsink-fan?
Several years ago I replaced a stock Intel HSF with a Cooler Master Hyper 212 Plus. I think the Plus has been replaced with EVO but it's the same idea - a monster heatsink with heat pipes and a large fan that will revolve slowly.
The downside is size, you need a case that is large enough since the HSF sticks out quite a bit.
There are better ones available but for less than $30 it's doing a good job.
