I have read many bad and many good reviews and comments about the lucite blocks like on DangerDen CPU blocks, most of the bad ones have said it cracked and the like. My question is have they improved enough to use and trust and when they crack how long does this usually take to happen?

Most crackage is the result of the consumers doing things to the blocks after they buy them, like over-tightening the barbs, or putting too much stress on the joint - i.e. thick-walled hoses with tight bends right after it comes off the barb.

The other reason is simply that they aren't thick enough. I'd personally never go under 1/2" thickness.

i've been using my maze3 for like 10 months .. the top never cracked for me =/ i tighten it a lot too

Yep. The way I remember it even the first ones were fine. It wound up being user damage if any happened.

If you're gonna get a poly top you should look for a few things.
Thick material.
O-ring seal.
No countersink or counterbore on the poly.
An added protection would be polypropylene or nylon hose fittings.

If the first three are met, I'd be 97% confident. If all four are met, I'd be 99% (same as a copper top).

peace.

Here's a useful discussion at procooling. From my reading, metal tops are more foolproof than plastic ones. You pays your money and takes your chances.

I've yet to have any problems with my lucite tops on the Maze 3 after about qa year of use. However, a friend of mine who also uses lucite tops has recently had them start to break and damn was he ****ed. His wasn't anything that he had done to it either which is most likely the cause under most circumstances but what happened with him is that the lucite cracked around small metal bolts that connect the top to the bottom of the block. It happened to his chipset block several months ago and he just marine gooped that one up since it was rather small, but recently (couple weeks or so ago) his CPU block did the same thing and now he swears by the copper top. Personally I like the look of the lucite tops and so far mine are doing pretty well through normal wear and tear as well as some extreme handling like being taken on planes across the country. Like joe said, you take your chances with the lucite, but if you follow unloaded's advice you should be golden.
