Case for TTSH ARP 2600

Thomann effect pedal case Rockcase RC23010B (http://www.thomann.de/gb/rockcase_rc_23010b_effect_pedal_case.htm) can be made to work with TTSH. This is mm-game but it fits. I also ordered the Belton RBL2AB3C1B spring-tank from Banzai Music. Now I must decide how will I fit the power supply. I think I am going to build it in an external case and bring the +-15V with XLR-connector to case.
