I'm running a home lab environment and my main storage server and plex-machine was occupying my spare storage room, have been using a bigtower for this over the last 8-10 years, finally got my shed insulated and invested in a server rack. Bought a cheap 4u chassis for my plex machine, but this had limited capacity for hard drives. I came over X Case via a friends recommendations. Delivery was very fast, no issues there (apart from the ATX psu bracket was missing, no big deal, it was sent the day after). The chassis itself far exceeds expectations in terms of quality, it's heavy and solid. Heaps of room for activities. Internal cabling is great, a bit long but that is never a bad thing. The HDD trays are excellent, good quality and has (as advertised) a very satisfying click to them. A screw-less solution would be a welcome addition. Back plane is also very high quality. Internal fans are very good, a bit noisy for my taste. The only issue i found is that the hot swap fan-shroud use a non-standard connection, it would be a lot better if it had the standard 4-pin connection at the base. This would make fan replacement a breeze. The airflow is excellent so you really shouldn't need to switch these out if noise is not a factor. There are no 60mm fans for the back of the chassis, I bought some Noctua NF-A6x25 and they fit perfectly. For the CPU cooler i used a Noctua NH-D15. this fits "almost" perfectly, it's about a millimetre or so too tall but taking care when closing the lid works fine. I also ordered the rail kit which was excellent, high quality and tool-less (although tools are needed if you have to adjust the depth naturally).
