NK4 with parts from EU


I’m looking for budget friendly parts available in EU (amazon.de or ebay.co.uk), I would like to use Fractal Node 304 case (or similar) with Mini-ITX motherboard, but the issue is that components posted in NK 4.0 guide are not available (anymore) on amazon.de and now I’m in dark as don’t know which one would fit my requirements with max 4 3.5" drives (raid) + 1 SSD for OS.
Did anyone build it lately from parts available on amazon.de if so, can you please share list of components ?

For me it’s important that it can play GoPro videos directly to TV (via hdmi). As it will serve as family NAS (a lot of photos and video material)
