It was a 29gal rimmed tank i got from LFS, i used a box cutter to convert it to rimless.
I was lazy to clean up residues from the silicon.
here's a Guide:

I also have a 10 gal which has been converted to rimless with no problems, i would recommend a tank with black silicon, most tanks 29 gals and above has ticker glass.
