Lian-Li PC-O5S Review

Let’s say that one day you woke up and thought “Hey, I need to hang my computer on the wall”. You immediately run into a problem: No one offers a computer case that you can hang on the wall. That is, until now.

The Lian-Li PC-O5s is a wall mountable, stand mounted, or desktop format case. I do believe it’s the first mainstream case to offer those three (3) options. The PC-O5s is the ITX version that supports a radiator in the top. The PC-O5 does not support a radiator, the PC-O6S fits mATX, and the PC-O7S fits ATX motherboards.

The case is entirely meant to show off your components, and your build. There is a glass pane that shows almost the entire case, and the internal design lays out the hardware in a way to show it all off.

  1. Nice review Mos. This case seems like a clear effort from Lian Li to offer something in the realm of InWin’s higher end concept cases. These cases looked amazing when we saw them at CES. Some people will balk at the price tag but this is a high caliber case that looks incredible. 90% of the people that walked by on the show floor stopped to look at them when we were at the booth.

  2. A great review as always Chris  :D
    As much as I love this case two things limit it in my eyes –
    1) It can only accommodate a 190mm GPU out of the box.
    2) It’s price tage in the UK – £280 ($417 US) erm sorry but no chance would I or many others pay that.

  3. Yeah, it’ll definitely take the right buyers to move these things. I do think it’s worth it, though. In terms of design, materials, workmanship, and aesthetic. It’s just got to be the right combinations of wants and financial resources lol
