Reviews like this can really hurt average consumers.
I have first hand experience with R13, with 3080 + 12900k. I bought it 5 months ago, because I needed a new PC very fast for work, and Dell is shipping with their own 3080, so I could get it in a week. Last week I bought a new board, new house, new AIO and a new PSU. My i9 was throttling just from opening several tabs in Chrome at once, instantly reaching 100 deg. I decided to repaste the CPU after 2 months, and I was amazed I found completely dry paste on the CPU! It helped on my idle temps but I was throttling like 10 seconds later than before under use... (I bought with the Kryo cooler btw, 4600 USD in total at the time).
I had to replace the PSU because the fans started to make rattling noise after 3 months. They changed it for free, very fast, a technician came to my place.
I had build almost a completely new PC, because the mb is not reusable in other case, the case is not reusable with other boards (not to mention that it cannot take bigger radiators than 120mm), and the same goes to the PSU as well.
ONLY buy this PC with i5!!! But even then, you can find better deals, both performance and price wise then this crap.
Silent? It is the loudest PC I ever owned in my life, and I started in the 286 ages.
It's barely worths 2 stars, the LED was the only thing I actually liked.
