What do you mean by 'hosts'. You mean a heatsinks? Or a little box to put things in?
I'm just gonna use this heatsink: http://www.dealextreme.com/details.dx/sku.9865 with my labby, no need to put anything in a box. Then for the driver, I'll probably just leave the board bare. As long as it isn't touching anything, it's alight. Like the boards on the scanpros, those are bare as well.
im sorry i should have been more clear.. im looking for DPSS lab host. i was gonna try my hand at making a DIY DPSS labby. like this http://www.youtube.com/watch?v=Fn0QVDEpe50
