This is a spec for the Node 304 with some extras to help with cooling and noise and cabling:
My basket at Overclockers UK:
PSU has been changed to a modular variety to help reduce cable clutter. It is 140mm as recommended for compatibility with long graphics cards.
GPU has been changed to Sapphire Nitro+ which is less thick (2.2 slot). If you want to take a risk with the thicker Strix (2.5 slot) that's on you because you'll have to send it back if it doesn't fit. The Gigabyte Windforce (2 slot) is cheaper if cost needs to come down although it's often said that the Sapphire has the better cooler (which has 4 heatpipes v Windforce's 3).
SSD has been changed to M.2 form factor (goes directly into motherboard M.2 socket) so that you have more remaining space for when you add another (regular) drive/s. Plus gets rid of the need for two cables (Sata data and SATA power).
Fan splitter added. The Node 304 has a fan controller for the case fans. However, it's only two speeds so you wouldn't have the control over them that you would with the motherboard fan header. Being Fractal fans, they'd probably be low spinning and silent even on the second speed. But the other benefit of the fan splitter (in case the first is redundant) is what the reviewer in the video pointed out - the location of the fan controller and needing a molex means passing more cables through to an awkward spot. Using the fan splitter, you don't need to use the PSU's molex cable, and the splitter goes into the SYS_FAN header on the motherboard.
Finally, CPU cooler added. Adds to cost but if you're gonna do it, might as well do it right. i.e. If a small case like this happens to support tower coolers, then they are extremely useful with helping cool not just CPU but removing hot air from inside the case and pushing it directly to the rear exhaust fan. The stock fan that comes with the CPU blows air down/sideways and it goes everywhere. If it helps - if this system was for me, and the total needed to come down, I'd go with the cheaper 2600 processor in place of the 2600X, because I wouldn't notice a few MHz less as much as I'd notice temps and the noise caused to cope with those temps.
Back to the actual cooler - the Brocken 3 is assymetrical and massively offset away from the memory slots so seems a good choice, not just so it doesn't block the memory slots, but also because it will leave more room for where the (regular) drives go, than a cooler that will sit closer/on top of the RAM.
If you need cheaper, switch 2600X to 2600. Switch 3200 for 3000 RAM. Get the Gigabyte instead of the Sapphire. And ditch the Brocken 3 cooler and just go with the stock cooler.
The splitter and the velcro (or a few extension cables etc) are the sort of things that OcUK staff have said they can usually throw in free of charge if you ask them. And indeed they've been nice and done me the favour a few times.
