Has anyones aquaclear HOBS ever overflowed?

No, I understand, I think you're missing the simple physics. Water takes the path of least resistance. If the back of the filter is higher than the front of the filter, the water will flow to the lowest point which will be the tank. Even with the baskets lifted there is plenty of room for the water to flow around or under it. The sides and back are built higher for this reason. I've been using Aquaclear filters for probably 20 years and have had some seriously gunked up but have never had one overflow onto the floor.

True. The filter has a hole underneath where the peg from the plastic spacer can be inserted then it can be adjusted to the preferred angle. When the filter is dirty it will flow both out of the output and around where the intake tube enters the filter so it wont overflow out of the filter casing.

Main reason I dont use aquaclear

This was BEFORE AQ's had the plactic foot on the bottom. Back in the day they had a little tap that was on the motor housing and you had to cut the tab to size to fit the angle of lean you wanted. The "plastic spacer" you speak of is a newer design of the AQ I used back then.

Actually my filters are all set to lean forward a little bit as opposed to leaning level or backwards.

The over flow came out from the little are before the media basket area. the force of the incoming water was enough to rise up above the filter top of the filter and spew on the floor. Because it was leanig forward Im sure alot fo the water flowed back in the tank but enough came out in order to empty most of my tanke throughout my 8 hr work day. (Think if turbulent water in a river, even though it is going down stream - the path or least resistence- with obstructions the water can rise up and abve the rest of the water in the river. Well that is what happened in my case) The media basket floated up- and that solid section of the top made the flow rise up and over the side, even though the majority flowed back into the tank from the front because of the angle it was at, but over time that slight over flow still emptied the tank.
Maybe its is something you'd have to see. Either way, it was my falut for not cleaning my filter - and maybe Hagens a little too because they chanegd the filter design years later by added the media backing locking tabs.

I never had this happen, but I see a simple solution. The left side should back up first (and get a bit higher) since its the pump side of things, prefilter, so it has the highest pressure. If you drilled an overflow safety slot at the top of this side of the filter partition, then the water will pour back into the tank instead.
