Hi, this could be considered a double post but this seems the best place to get help on the following issue so...
I've just had to install a new CPU heat sink and fan and although I was told a particular one would be the same as my previous it turns out to be a tiny amount taller. This is just enough 5-7mm to make it not fit the case.
The internal layout makes other shorter alternatives awkward for other reasons and I also cannot easily return this one so I'm trying to work out how to either modify the unit or the case to fit. I'm trying to work out if filing down or sawing off a tiny bit of those copper prongs is an option but if not then I'm wondering if I might ditch the old metal sleeve (not pictured) that fits the chassis and then using perspex or some other material to make new sides and a top for it.
Any ideas on which material would be a good choice? I'm not that concerned with looks.
