    X-Case 4000 Big Open 4u

    This is 3d server case I purchased from Xcase. Good product and good customer support as always. Much cheaper than in Sweden and still fast and very affordable shipment.

    Perfect for Gaming Rig Rackmount Conversion

    I wanted to rackmount my gaming rig to make more space on my desk. This case turned out to be perfect for this. With a bit of velcro tape and some zip ties I even managed to mount the AIO. I thought I was going to have to switch back to air cooling but this case fits the 240mm radiator with no problem. Only issue I found was with the front IO connectors. On my unit the HDD LED and power LEDs are mislabelled in place of each other. Easy fix but confused me for a second. Overall I love the case and I plan to order another when I build my next gaming rig in a few months.

    Machine Learning GPU Setup - Excellent Case

    We've bought many cases from xcase.co.uk over the last 8 years, this case is maybe my new favourite. Our configuration is a full size ATX boards, with only M.2 SSDs HDs on the motherboard, and two GPUs for machine learning. No external Hard Drives. And of course a PSU. If you're building a setup with no external HDs, or low external HD setup I really recommend this case. It's extremely well built like what we've come to expect, solid but not too heavy. There's two horizontal bars at the top of the case you can see in the video above, which you can mount drives to, in our case we removed those bars all together to improve access, they can be removed easily by removing 4 screws, this then gives you a nice clean box to work out of. It comes with 1x 12cm fan at the front. It's a loud fan, if you care about noise you're likely gonna change it, as we did. We mounted 2x 12cm low noise fans at the front, and 2x 6cm fans at the back. Airflow is really great, because you have plenty of space for fans, but also the air flow is clear without anything in the way. There's some filters for the front fans that can be removed to be cleaned without having to open the case. The case is still much bigger than a full size ATX so you'll have some empty space, but that's a good thing again with air flow from the fans up front, giving them some space for the air to move in. 2 LEDs up front, a power LED and a HD access LED, work well, and a power button. There's a pair of USB ports up front as well. Overall I would really recommend this case if you want something clean and you don't need any bays or very few bays and you're basically looking for a good price for a case to hold your motherboard and cards. The outside is finished in black.

    Rackmount case for my studio build

    The 4U case is great for my needs (recording studio with wheeled rack portability) and everything fits in nicely. I was worried my cooler wouldn't fit as I needed a real silent and hefty one, but after being told I can fit a max. 155mm cooler, I opted for the Scythe Ninja 5, and it fits nicely. I put two Noctua 120mm fans in the front and two 60mm ones in the back as exhaust. It's cooled well, but the only negative I have about the case is that you can really hear the air being moved around/out of it. I've messed with the PWM fan settings, but I wouldn't say it's completely silent (no overclocking either). It's nothing that really gets in the way of my recordings though, it hasn't been that audible. All in all a great case, and arrived nice and quick too.

    Excellent case, plan to buy another

    I've now got TWO of these 4u cases, one for each of my His and Hers gaming rigs; It's a brilliant case with no frills, loads of space and a build resembling a tank. A word to the wise; if you are running toasty equipment (95W PSU and 175W+ GPU) you're gonna need to utilize those fan bays! That being said, I'm running 2x Noctua 120mm up front and 2x Noctua 60mm at the back at 80% duty cycle at all times and never see unruly temps! Strongly reccommend!
