techgeek :
I wasn't recommending it if the case and cooler hadn't been bought already. But if the parts had been purchased already and were not returnable (or reasonably returnable), then sometimes you have to make do.
As for metal rubbing, the system was used like this for over two years until he bought an entire new system. There was no wear on the top of the heatpipes whatsoever. There might have been some marks on the inside of the panel, but these weren't visible from the outside. There was a slight bulge in the side panel as I said, but there were no other issues.
"but I've seen where the cooler is like a millimeter too tall, and you can still get the side cover on. It pushes out the middle of the panel a bit, and it was noticeable if you looked, but it worked."
That actually
is recommending it.
This is a worldwide forum, and these statements said here will be read for years.
5 years from now, some kid who is currently 9 years old will read this, and think. "well,
techgeek said that metal on metal rubbing is OK, so..."
And then toss in someone who accidentally kicks the side of their PC...
I'm just saying...you have to be cognizant of the wider audience.
"...but it worked" is a recommendation.
