Check this out biatches! Somethin' actually happening (something new from me :D). Went to the local Etra and told them to cut me 14 pieces of 40x200mm and 12 pieces of 20x200mm from 4 mm tight polycarbon.
Cost: Free (I was going to take their souls if they don't do what I tell) Okay really those pieces were about 17.69euros.
No, they are not cut with laser, propably with tile or table saw. That's why so rough look, well... At least something to do to finnish 'em.
Now just gotta find nice screws and get the aluminium.. Maybe something happening again at next week!
And yes Drakmin, I ended up to the PC... Maybe on more powerfull amp using the aluminium so these can really be heatsinks ;) But that will have to wait for now.
(Yes there is pieces for the other side too, they are safely wrapped on plastic still :)
