I sent my Rackbrute 6U back and I'm currently waiting for a Refund from Bax-shop.co.uk it had overheating problems versus the simple Tiptop happy ending cases/power I already have. I won't buy anything from bax-shop again, even before Covid their email response was slow.
I need to find someone with a CNC router and I'll design and build my own, starting with the Tiptop uZeus power I have, then probably buy om Konstantlab Power at a later date.

Enjoy your spare HP, don't rush to fill every last space, this is not like filling sticker books. Resist the urge to 'complete' your rack, its never complete so just relax.
