I wouldn't advice Cyberpower or Ibuypower in normal times, but with parts availability what it is, it can be justified if you go in it thinking like a builder, not as someone buying a finished product. So make sure you know exactly what parts you're putting in; no taking the "standard" PSU or RAM or just going with the liquid cooling "upgrade" which is frequently just a cheap 120mm AIO to save themselves money on big air coolers that might cause RMAs. And assume that it's assembled incompetently and when you get it, basically rebuild it on your own.
Places like Maingear and going up from there, places like Falcon Northwest or Puget Systems, are more proper boutique builders, where you pay for the quality and you have a reasonable expectation that things are put together correctly.
