I just got this lovely baby 2 days ago,when i want to open the case by screwdriver,the screw itself easily ‘melt’ causing 2 of the 7 screw protecting the case cann’t be opened because of have been damaged,i have some suggestion :
Next time please use more high quality screw,it seem on RB 1100 mikrotik using screw which made from aluminium alloy not a pure steel or aluminium mixed with steel,this is causing the screw to easily melted when putting too much pressure on it when opening with screwdriver,i think good screws only cost you another 1$ for every 30 pieces?.
Please don’t tightened up the screw too deep,in this case because of Mikrotik put the screw too tight,i need to put some pressure to open it
Now i need to borrow a drill to open it and also a air compressor to clean it from casing steel and aluminium left over which going to be on some area on board,i just don’t want to cause short circuit just because of these tiny fragment ,i don’t either this case is belong to rma or just small Quality Assurance glitch?but eventough if it possible to RMA,i am not going to spend 60$ to sent over to lithuania(wifi-stocks.com) and another 60$ for return + 90$ taxes ,i am quite dissapointed by this minor issues but overall is really a great product.
i use the correct screwdriver(4 junction one,i don’t how to call this in english lol),does mikrotik using automatic screwdriver drill?because if so,it’s explains the really tight screwing,these 2 screws i cann’t open it again as i was become pissed off and trying to manual drill using the screwdriver ,oh well i need dreamel mini drill to open it .
It requires a #2 phillips bit. Most 3mm screws use a #1 phillips bit.
The #1 bit will be loose in the #2 screw socket and has the potential to ruin it.
Even armed with this vast knowledge, I only used a #2 driver and still stripped out one of these screws trying to open an RB1100. The screws are fragile.
IMHO They are also torqued too tight.

PS I was able to remove it with an awl and small hammer. Driving the head the correct direction until it became loose.
I couldn’t use small hammer as i am afraid it might damaged the Serial port,because one of two screws that cann’t be opened is on the back of the casing,i cann’t experiment much with ‘violence’ with these stuff as it’s expensive for my families,and need to indent couple weeks to order one . I am waiting for my mini drill dreamel to arrive soon,it has small drill sets that use mostly on r/c modelling hobby.
Bad news,using small drill no use,failed ,the drill head melt :/,can you post the picture of the awl and small hammer?i am from non-western country,kind of confused by the term awl,only found this kind of awl on the internet : http://en.wikipedia.org/wiki/Scratch_awl.
We have talked to the factory to decrease the power used when assembling the case, and also to include extra strength coating on the custom screw heads.
Yes, that is what I used. Place the sharp point near the outside edge of the screw head and lightly tap with a small hammer in a counterclockwise (anticlockwise) direction. If you have the correct angle, the tip of the awl will dig into the screw head enough to grip it. The light tapping of the hammer is like an impact wrench and will loosen the screw.
This technique worked for me but I also have many years of mechanical experience. In the 1970s I worked as a motorcycle mechanic. We had similar problems with Japanese motorcycles which used many tight phillips head screws.
and also a air compressor to clean it from casing steel and aluminium left over which going to be on some area on board,i just don’t want to cause short circuit just because of these tiny fragment 
,i don’t either this case is belong to rma or just small Quality Assurance glitch?but eventough if it possible to RMA,i am not going to spend 60$ to sent over to lithuania(wifi-stocks.com) and another 60$ for return

,oh well i need dreamel mini drill to open it
