So I'm just gonna say, the aesthetic/design language of PS5 is really likable. But I felt that way the first time they showed it off. It's the actual size where my issues come into play. It's just almost comically large; maybe a different approach to the motherboard design and arrangement (while still having things function the way they'd want) could've helped in getting the physical footprint smaller.
Some of the shots, particularly if you lay it horizontal, make it look better on the physical footprint front, but vertically it's something of a Goliath. Ultimately I don't think this is going to bother the hardcore or most core gamers too much, but I can already see them planning for a slim model for the early stages even at this time, because I'm curious how casuals and mainstream types will take to the size of this (maybe they won't really care all that much.
There's also the subconscious signaling that if you make it look bigger, people'll think it's powerful. You know, American muscle car kind of thinking, but systems like the Turbographx-16 were designed with that in mind too (to not-stellar results for that system, sadly).
