Ok i will try to find a 1200 or a 4000.
Is the 1200 rdy to be built into a tower from scratch or do i have to mod the motherboard to fit in a "normal" atx tower?
If you buy a tower that is especially for the A1200, then you just screw it in.
If you want to put it into an ATX case you bought from a PC shop, be prepared for a lot of angle grinder, drill and dremel work on the case to get the motherboard to fit.
