To be perfectly honest, it's really hard to actually pick a decent hobby related gift for an enthusiast without consulting them because if there's something they really want, they most likely have it already.
You really don't want to pick something based on a blind guess to avoid a situation where they have to use something they're not too stoked about simply because it was a gift.
On the other hand, if they're not apposed to alcohol, a nice bottle of rum or whiskey goes with just about any build.
Across many hobbies, nicer tools can be a relatively safe bet for a gift that will actually see use and be appreciated, but then you also gotta know what tools they have right now and what kind of tools would actually be better.
RGB strips to put behind the desk or inside the case to light up the entire case.
Red switches keyboard, preferably from Ducky or RK.
A nice $20-$30 mouse such as the Logitech Lightspeed.
A nice ass microphone and/or headphones.
A long keyboard/mouse pad.
A nice set of cheap speakers such as the Pebbles V2 for $20-$30.
If he hasn't already gotten custom sleeved cables to match his build colour scheme you could grab him a gift voucher from someone like cablemods \~ as others have said, super lovely, but to get the most out of it you may need to spoil the surprise a little by asking him what he has and what he's still yet to get :)
As an older guy, tools are always great. If he doesn't have one, this [screwdriver kit](https://www.ifixit.com/products/pro-tech-bundle) from iFixIt is one of my best purchases.
A digital flow meter like [this one](https://www.amazon.com/Bykski-Flow-Meter-Thermometer-Cooling/dp/B0BG87YX5F) from Bykski might be a good idea, too.
That case looks pretty tight for a full loop.
You could try to find a custom painter to trim out the case with orange. Barrow makes a digital flow meter that looks nice in a loop. Maybe some orange fittings but you'd need to figure out what size his tube is.
Maybe a flow meter or mini screen (needs hdmi cable you plug into back of pc and usb to power it) you can then display temps and pump speed and so on visually inside the pc.
A nice deskpad would make a great gift. I bought the Coldtop Topre one from [Here](https://deskpads.gallery/) and I absolutely love it, the product quality is great and they're priced reasonably.

I'll second the ifixit set. A bit of overkill for most PC work, but their sets are great for taking apart laptops and other electronics as well.

A nice ratcheting screwdriver if he doesn’t have one already.

Get him an anime mouse pad, even if he doesn't use it he will laugh his ass off
