The real issues with a full DC system is finding compatible electronics to meet your wants.
Want to play a video game? Gotta either convert your DC to AC so the AC to DC converter can swap it to the right voltage. Either that or you need a DC DC buck/boost converter that you can trust to not trip out and fry your system.
The systems exist for local full DC power, but they are likely more expensive, designed for vehicle/RV use (and thus smaller than the typical home use item of the same variety) and more difficult to repair because they are made smaller.
Not saying you can't do that, only that there are plenty of tradeoffs to take into consideration due to the differences in scale of devices built for AC vs devices built for DC.
