Hey everyone,I have a UniFi Toolless Mini Rack in my closet with the following gear:

• UDM Pro SE
• Switch Pro Max 24 PoE
• USP-PDU-Pro (the power distribution unit)

Everything is running fine, but I’d like to add some active cooling to keep temps down in the enclosed closet (my 8TB hd is running at 58c, so its not on fire, but its above recommended temp). I’m looking for the easiest fans to integrate into this kit.I can easily power fans via a regular AC outlet or USB-C (I have plenty of ports and outlets available), so power isn’t an issue. I’d prefer something quiet, simple to mount, and relatively clean-looking if possible.What fans or fan kits have you guys had the best luck with on a similar Toolless Mini Rack setup? Any specific models, mounts, or 3D-printed solutions that worked well?Thanks in advance!

Extra context: This is just a standard hallway 9ft tall closet with a few shelves that is central in my San Diego home. There's a decent sized gap under the door and I'd prefer not cutting a hole out of the door for a fan/vent if possible. I may be adding a few more pieces of gear so I wanted to sort some fans or something to help mitigate temps.

Trying to decide between the Panasonic UB820 and UB450 for dedicated 4K Blu-ray playback and wanted feedback from people who’ve used either (or both), especially on OLED setups.

My current setup:

• LG C2 77” OLED
• PS5 (currently used for 4K Blu-ray playback)
• Sonos surround system:
  • Arc Ultra
  • Sub Gen 4
  • 2x Era 100 (rears)

Audio is fully handled by Sonos, so I’m only focused on video performance and I stream alot of stuff from my buddies plex server/apple TV.

What I care about:

• Pure 4K Blu-ray picture quality
• Dolby Vision performance on OLED
• HDR tone mapping / highlight handling
• Overall cinematic image quality (disc playback only)

Main question:

Is the UB820 noticeably better than the UB450 in real-world picture quality on an LG C2, enough to justify the price difference over the UB450 and even the PS5?

Or is the UB450 already close enough that the UB820’s advantages are fairly subtle in everyday viewing?

want action anime plz I’ve already been watching a lot of the mainstream/recent hits like
Frieren, Fire Force, Jujutsu Kaisen, Chainsaw Man, Demon Slayer, etc.
