As per the title, it's a general purpose system. Not entirely for gaming and not entirely for other purposes either. My first time building myself. Very scary with all those expensive parts. It seems to work though.
I'm using this system for everything outside of work, so I can leave my work computer for work (I'm a programmer). This is important because I killed my work computer's SSD with page file thrashing from too many things open - 450TB written, and I couldn't let that happen again.
I'm going to use it for:
-Development (for stuff outside of work - side/hobby projects), including using VMs
-VR (games, videos, development)
-Watching videos (including with SVP motion interpolation which is demanding)
-Music production, video encoding and other side hobbies
-Multitasking (eg hundreds of browser tabs open)
Problems I encountered:
-One of the motherboard standoffs was missing in the case, so I had to unscrew and take out the motherboard, screw in the spare standoff, then put the motherboard back in.
-I created an install from the latest Windows instead of using the USB that came in the box, to avoid an error I read about. Something about having to disable IOMMU in BIOS.
-Windows didn't install, and the setup crashed with a memory error. I went into the BIOS and turned the memory down to 2933 from the default 3200. It worked fine after that. I should probably run memtest but haven't gotten around to it.
-Wi-Fi was not working. I had to set it to 'enabled' in the BIOS instead of 'auto'. It was unusable (like 5kb/sec) with Bluetooth devices connected (it has a combo wi-fi/BT card) so I used a LAN cable anyway.
-The CHA_FAN3 header is dodgy, it only controlled my 3-pin fan's speed once or twice and then went back to full speed. It looks like other Asrock motherboards also have this issue. I need to buy a fan splitter.
-Threadripper was a bad idea, but not for the same reasons that everyone else says. It generates far too much heat. This cooler is obviously insufficient at stock clocks and on load the temperatures are constantly in the mid-60s tdie. On idle, I can't spin all the fans down really low because so much heat is being generated even on idle, so it's a bit loud for me. I wasn't willing to take the risk of liquid cooling and didn't want to worry about clearance issues with the NH-U14S.
-Restarting in game mode to play games that would otherwise crash is a pain. It's possible for some games to work by using a shortcut that opens the game with affinity set to half the CPU cores.
I also bought a Windows Mixed Reality headset (Lenovo Explorer) and it's a fun toy. My Bluetooth receiver is not good enough to use the controllers while on my bed (for 'those' games/videos), so I might need to buy an external one.
I'm also using the monitor for my work computer (MacBook Pro). The keyboard and mouse switch between computers by pressing a button.
I have a total of 35TB in the pictured row of external hard drives under my desk, although they aren't all connected at the moment.
