I'm considering the Lian Li O11D Mini V2 for a system upgrade, but I noticed the PSU intake doesn't appear to have a dedicated dust filter. Since the case will probably sit on my desk rather than on the floor, is this something I should worry about? Does it require significantly more cleaning, or is the side-mounted position relatively safe from dust? I'm also replacing the power supply and would prefer a Seasonic unit. Would it be worth buying Lian Li's PSU with the magnetic filter, or would a generic magnetic nylon filter work without restricting airflow or looking awkward on a white case?

The rear panel uses a metal grille, but that shouldn’t necessarily be treated as a fine dust filter. Some product descriptions may call it mesh, so it’s worth checking clear photos or the manufacturer’s documentation rather than assuming it provides full filtration. Either way, the lack of a dedicated filter is manageable with periodic cleaning.
It’s probably not a major concern. A side-mounted intake that’s sitting on a desk will usually collect much less dust than a bottom intake on the floor. Just open the case and clean around the PSU every few months, depending on how dusty your room is.
You can add an inexpensive magnetic nylon filter if dust becomes a problem. It doesn’t have to be the Lian Li-branded one, although an external filter on the side may be noticeable, especially with a white build. You could experiment with placing one inside the case, but make sure it leaves enough clearance and doesn’t restrict the PSU’s airflow.
I was considering that, but I’m not sure I’d like the look of a filter mounted on the outside. I may try an internal filter later if dust turns out to be an issue, but regular cleaning will probably be enough.
That’s what I was hoping. Since it’ll most likely be on my desk, I may be overthinking it. I’ll keep an eye on it and clean it regularly.
