Question about Lian-Li PC-O11DX Dynamic

Yes.
Extracted from the website:

Fan

(Top) 120mm x3 / 140mm x2(Option)
(Side) 120mm x3(Option)
(Bottom) 120mm x3 (Option)

Radiator

120x 360mm / 120x 240mm / 140x 280mm

280mm is just longer than 2x140mm but as it supports 360mm in length anyway it's fine

ok thanks for your answers so I'll take a 280mm

Hello,
No chance having two 140mm top in mine they already take up the whole depth of the case. I think the max configuration is 2x140 or 3x120 top.
