Well, that, and the CPU only has so many PCIe lanes and adding ports beyond that requires a switch. Also, if they have two 16x slots to allow for dual graphics cards those eat up quite a few of the lanes (even if one isn't actually 16x). > > Here, Linus is showcasing an 8-drives storage machine in a Fractal Define= R4: > https://www.youtube.com/watch?v=3DDpJViwtct5g > And here a system with 18 drives =F0=9F=A4=AA in a Fractal Define 7XL: > https://www.youtube.com/watch?v=3DFAy9N1vX76o I think a lot of the consumer cases have been moving away from accommodating hard drives and making more room for gigantic GPUs. All that said, I have largely abandoned the crusade of trying to squeeze a dozen hard drives into one host, in favor of distributed filesystems. If you're only putting a few drives per host and having more hosts then it becomes pretty easy to find hardware that works. Finally, for any system that will be running 24x7 I'd suggest optimizing for power use per unit of computation (which is a hard figure to find), and idle power use (unless you actually do something that keeps the server busy 24x7). Usually newer processors will do better here. The up-front costs of a CPU are likely to be dwarfed by the cost of powering it. ARM is of course advantageous if you don't need too much horsepower or RAM. Unfortunately ARM boards with lots of RAM are crazy-expensive so it isn't a great option if you need more than a few GB. There has been interest in using mini PCs from corporate used sales as servers, and I'm thinking about building storage around a solution like this. The drives would need to be external of course, but USB3 is plenty fast for hard drives. However, it is hard to find easy to lookup metrics on power use and stats like USB3/etc - most filters on used product sale sites just have filters for RAM and maybe CPU. You do need to be careful as some of those systems could have high power draw or lack USB3 or even gigabit LAN, making them unsuitable for 24x7 storage. The price and form factor can be very attractive though, and power use still tends to be low since large companies do think about those costs. -- Rich -- Rich
