Ok guys, i did it, i redid the frane in to an aluminum one and it turned out extra!!!
you can see it on the video below

The aluminum alloy that i am using is durafix, and it is insanely strong for welding, i did a weld and i smashed it with hammer trying to tare the weld and make the weld brake, the only thing that broke was the cube piple it self... and i used really small ammount of it..
You can see here, i welded, well its more like soldered only 2 sides, see how much smashing it has been trough and still survived
Also the frame and welds, few pics... it will be done tonigh, and finally i can start painting tomorrow, i switched entire case upside down... i ended up with 2 cases
I hope you like it

, also guys if you ever try to do these welds, they dont stick to steel, only to "Coloured metals" so you can use steel plate instead of the one i have been using, i used Azbestus boards so i can get my nails in and keep it all at the right angle... Be advised, azbestus is highly cancerogenic... and the fumes are really rough! but i needed to keep temp and it is extremely good insulator...
