I was tired of having to remove the mobo every time I changed a cpu to tighten the waterblock mounts, which get loose alot. I drilled some holes large enough for a screwdriver in the tray that line up with the mobo holes. So why don't cases have these normally?

Most peeps don't use waterblocks bro, I personally prefer clips since it makes on/off time easy... Nice mod though dude, that's what it's all about, making the good things better and the better things HARDCORE!!!

No trays have holes like that cause mobo manufactureres are always putting stuff in funky spots for different porcessors and formfactors, so why waste the time and effort if it won't work for most people?
