Alright.Thank you all.I found the exact casing I lost,but this time NOT.The worst thing is it was in a PC shop about 1.3km far from ma house.And it was the last one too,But this time made no mistakes.

I disassembled it in 1 hour after purchase(For modding purposes)So Actually cant have a pic now as it is like 50 parts now.Will post a pic in about 2 months or so.

Thanks once again.
