A box by itself will not dissipate heat naturally without some kind of ventilation. You could have any size box that would fit those items and it would still store up the heat without some kind of ventilation system. You’d need forced air with fans or even just slits in a box, depending on how much heat is generated by those items. A closed system is not the solution here, but of course, having a tightly packed item isn’t the best either. You’d probably need at least half an inch to an inch of airspace to allow space for fingers to install these devices. If you use fans, you’d need more space because the width of the fans would probably take up extra space. If you just use vent slits, it would have to be enough room to get your fingers in the box to install the devices.
