Wasn't offended, more concerned that I might have put you off modding computers, or p****d you off by making it sound easier than it had turned out to be. For future reference, I tend to lean more towards understatement than exageration.

Close, but not quite - look again. The lugs of the socket that the heatsink was latched onto turned out to be stronger than the bond/grip/whatever between the socket & the metal pin bits that were soldered into the motherboard. [plus I used Arctic Silver, not the original chewing gum that Cooler Master put on it] That's 1 of the reasons why you couldn't pay me enough to use an ECS [aka Elitegroup] motherboard. It's not like the heatsink was heavy either, just a cheap aluminium Cooler Master jobby [good enough for an XP2000 that wasn't going to be overclocked, plus they wouldn't cough up for a decent 1]. Also, if I ever build a system for someone I don't know really well again, & they ignore my recommendations for hardware [I recommended an Abit board, they insisted on the cheap ECS 1 because they couldn't afford the Abit], I'll just tell them to find someone else to build their computer for them.

Stuck some tissue paper inside to stop dust again.
In all honesty, I think that tissue paper might be hindering airflow too much. Dust's only a problem if like me you can't be bothered to have to clear the dust out of it every month.

Unless "fishing" is a euphamism I haven't heard before, I'm not sure that excuse works. As I said previously, I haven't tried them before, so don't know how they rate in terms of a balance between airflow & dust filtering.

Probably the reduced turbulance on the front intake fan.

Out of the various options you've listed the 1 in/1 out is the 1 I'd forget about straight away, if they're close together you'll just have the intake 1 taking back in the warm air the exhaust 1 has just removed. That's why people don't make the rear fan below the PSU an intake instead of an exhaust.

The only thing that would bother me about that idea is what sort of residue the smoke might leave behind.
