Hi. I can for now only pick things up to a 1000 so this is what I've picked. Is this alright? https://uk.pcpartpicker.com/list/kDCZZf Also, the note "Some physical dimension restrictions cannot (yet) be automatically checked, such as cpu cooler / RAM clearance with modules using tall heat spreaders." makes me think. What is it supposed to be about? Does this mean those things might not be compatible inside with each other? Thanks in advance.
