Thread: Happy Ending Rack Master
I agree with Jim, I have a bunch of 2hp modules and to be usable you need at least 1hp space between them, I also find that some 2hp modules can get quite warm so I leave the 1hp gaps open for ventilation.
Enjoy your spare HP, don't rush to fill every last space, this is not like filling sticker books. Resist the urge to 'complete' your rack, its never complete so just relax.
