Good intentioned advice needed here before I send a web ticket for potential return, do have some options here, so bear with me while I explain.
What it is, have ordered a new Lian Li O11D EVO XL - Black (case) that is due to arrive tomorrow ... I have confused this case with a newer version that can accommodate my Actic cooler 420 mm size AIO cooler (even three of them apparently?) but upon further research and build preparation looks like I've ordered a case that can only accommodate typical normal sized 360 mm AIO coolers ... Dang
My options are >>>
1: Send it back to OCUK, but what would happen if I told delivery guy tomorrow I made a mistake and can he return to sender? I'm quite prepared to pay OCUK return postage and wait while it is processed. This is my fault, not theirs.
2: Accept case order tomorrow and send a ticket to OCUK and see where we go from there and order the newer version that looks out of stock just now but can accommodate my Arctic cooler 420 mm triple fan AIO ... Its a chunky cooler for sure.
Would not even open the box if above options are viable but would send back un-opened as delivered.
3: Accept my mistake and butcher the case to make my 420 mm AIO fit ... apparently it can be done after looking at some examples of this on Reddit ... not really ideal though is it, but cases wont wear out and are for life, so maybe.
4: Just take my mistake on the chin and order up a good and appropriate 360 AIO that will fit this case? Have now read some of the better 360 AIO can outperform my Arctic 4 420 mm triple rad ... if so what would be the best 360 triple rad to buy for this case and running an AMD 7950 3DX at only stock speeds?
Please help, know I've made a big mistake here and need some honest down to earth practical advice, spent a lot of money on this build, RTX 4090 too, just unsure how best to rectify my mistake.
Thanks.
