Well just did a check on my older version of the Corndell 1273 Nimbus - that we got free a year back from Brother/Sister in-law when they moved house and were going wall mounted and integrated shelves - and it will fit nicely with hand space around the side.
My bigger issue is: when on earth are more pre-orders opening up on Amazon.co.uk? - shakes fist at Sony and hopes to get in at day one.
I have got my Subwoofer on the left hand-side of the cabinet, so I might just even things up and place the PS5 on the right hand-side - stood upright - for maximum cooling.
It would be interesting to know what the power draw on PS5 was while the Demon's souls game was playing (in the trailer), as even with me retiring the PS4, I suspect my UPS that hides under the bottom draw might not have enough supply left - even if I place the 300watt Soundbar on the unprotected sockets.
