When I was remodeling my home server, I had old parts that I used to test the hardware and software, but keeping the parts organized didn't help lay out. It took a little effort to align the motherboard mounts, but gradually made small adjustments to get there. The instructions are written half in Chinese, but I managed it - I'd say it's like assembling furniture from Ikea, only more precise. Overall the quality is better than I expected. The only criticisms are that the posts for the PCI slots aren't screwed in to the same length, so the height isn't exactly the same. The PSU mount is for full size models only and I had to use an SFX adapter for the SFX PSU. But other than that it works fine for my use case.
