Getting metal cut ?

[Dicehunter]

Bit of a weird request but does anyone know where I could get a piece of thin aluminium sheet customised from an existing piece in the UK for a decent price that I can also send it to via mail ?

I have this motherboard tray cover for my 5000T and I'd like to mod it by cutting out 3 x fan shaped holes that line up with the fans behind it so it increases airflow while still making the back look neat.

most metal workers can do this. Even your average garage that deals in metal fabrication could do it. But they need the dimension specifics. Ideally, give them the old piece and they could replicate it with the modded changes.
