I know in the text of the Imgur album you mentioned that you could fit radiators of a maximum of 150mm in width, but it isn't mentioned the maximum length. There's an indication that the PCIe slot can be up to 327mm in length, but I don't know if that's completely accurate to the radiator slot or if there's some other obstruction (likely) above that limits radiator length.
I suppose instead of asking 20 questions I'll just lay out my challenge: I'm trying to do a full custom loop in the case with a 280mm radiator and struggling on how to fit the pump and res. If indeed you can fit something like
this pump/res combo horizontally without interfering with the GPU, then that may be the only option. I see there are tube holes on the back but other than something like the Eiswand (enormous standalone external rad/pump combo unit), I'm not sure how to use them. Can you fit a pump on the outside while having the hoses go through those holes?
Otherwise I'm thinking maybe something like the Eisbaer LT pump/block combo (because the Apogee Drive II is 5mm too tall according to the 55mm cooler height limit) plus a GPU block and a 280mm crossflow radiator at the top, but the Alphacool crossflow radiators (which have top-facing fill ports) are 334mm long so I worry it won't fit.
It's my first time doing an open loop, and so doing it for the first time in a small case probably doesn't help, but any advice you can give (or anyone can give) would be helpful.
