In that case, I think, I better go with L4000U/L4500U.
Also, for air cooler installation, if you need to remove the side bar, does it compromise the overall stability/steadiness of the case??
From the above topic, it seems the same issue with side bar on L4000U as well to accommodate air cooler towers.
I am wondering, if we can drill new holes with dremel tool or something and move the side bar backwards to accommodate air cooler without loosing stability of the case? Is that a possibility? Or side bar is welded with brackets without the option of moving even with drill new holes option??
