those 'bumps' are intended help to support the motherboard. It is up to
you to determine whether or not your particular motherboard will not or will be 'shorted'! If your motherboard has a 'ground trace ring' (a hole where a mounting standoff would mount) touching the bump, it is probably alright! (the motherboard is intended to be grounded there) If there are any components, any conductive traces, or anything other than a 'ground trace ring' sitting on the 'bump'; chances are very likely that you would have a
short condition.
I have recently seen on this forum, comments from someone who had assembled a new 'box' using an Evercase 4252; he layed down a small piece of electrical or duct tape to make sure he didn't short something out! Another solution might be to 'dimple' the center of the 'bump' to move it slightly away from the bottom of the motherboard; then put a small 'peel & stick rubber foot' (such as Radio Shack # 64-2346 : a package of 12 for $ 1.49 ) in the center of the 'dimple' to touch the bottom of the motherboard! Just make sure you place a 2x4 under the area of the 'dimple' that you want to 'lower' and use about a 12 ounce ball pein hammer (the ball end) and whack it lightly until you get the desired result.
I have recently purchased the same 4252 Evercase; IMHO is a cheap case, that verges on being a P.O.S.! (I bought from NewEgg, also; paid only $37 including shipping. Good case for someone with a lot of experience & knowledge for modifying and who wants something cheap to 'hack'! Would buy another if I had the need for it within the next 6 months! NOT a case for a first or second time builder! IMHO) I have'nt had the chance to do a 'trial fit' of the motherboard that is going into that case; if I have a problem, the offending 'bump' is gonna get cut out completely. For me a poorly placed 'bump' in the mobo mounting 'tray' is just a 'minor bump in the road of life' ! haha, I'm a poet, or something!
