Description

As a new edition of The Tower Series, The Tower 300 inherits the classic vertical case design but comes in an octagonal prism shape. It has amazing hardware compatibility, accommodating a 4090 GPU, a standard-sized power supply up to 220mm, and a 420mm AIO radiator. What's more, it can accommodate up to eight 120mm/140mm fans on the top, back, PSU cover and right side fan bracket. If you want to make The Tower 300 more visually appealing, you can purchase the separately sold 3.9" LCD Screen Kit and Chassis Stand Kit to upgrade the build; the former to display real-time component information and the latter for a unique view with a special horizontal placement. •P/N: CA-1Y4-00S1WN-00 •SERIES: The Tower •CASE TYPE: Micro Tower •DIMENSIONS: 551 x 342 x 281 mm (22.5 x 14 x 11.5 inch) •WEIGHT: 8.3 kg / 18.3 lbs. •SIDE PANEL: 3mm Tempered Glass x 1 •COLOR: Black •MATERIAL: SPCC •COOLING SYSTEM: Top(exhaust):140 x 140 x 25 mm CT140 fan (1500rpm •EXPANSION SLOTS: 4 •MOTHERBOARD: 6.7" x 6.7" (Mini ITX) •I/O PORT: USB 3.2 (Gen 2) Type-C x 1 •PSU: Standard PS2 PSU (optional) •FAN SUPPORT: Top: 2 x 120mm, 1 x 120mm, 2 x 140mm, 1 x 140mm ; Right Side: 3 x 120mm, 2 x 120mm, 1 x 120mm, 3 x 140mm, 2 x 140mm, 1 x 140mm ; Rear: 2 x 120mm, 1 x 120mm, 2 x 140mm, 1 x 140mm ; Power Cover: 1 x 120mm, 1 x 140mm •RADIATOR SUPPORT: Right Side(AIO): 1 x 360mm, 1 x 240mm, 1 x 120mm, 1 x 420mm, 1 x 280mm, 1 x 140mm •CLEARANCE: CPU cooler height limitation: 210mm ; VGA length limitation: 280mm(With power cover), 400mm(Without power cover) ; PSU length limitation: 220mm

I haven't seen very many full custom water cooling setups in the Tower 300 yet. It is a tight fit depending on what components you have to work with for sure. It took me a few days of planning and a couple days to really get it built like this looking super clean. But end results speak for themselves. I migrated most of my existing waterloop with the addition of a smaller reservoir to this case. It all fits.. barely! I was going go go hard tubing but after a little trial and error decided against for ease of maintenance in such a tight space. If you take your time, soft tubing can looks great and SO much easier to deal with. The case itself isn't exactly what I would consider Micro-ATX size as it's quite tall and still has a decently large footprint. But you definitely save desk space in depth. Love the vertical GPU look and the Pump/Res being the centerpiece. There were 2 mods I had to do to get the airflow optimized and 1 to get the my GPU to fit and still use the included cable cover at the bottom. Mod #1&2, Get better airflow. The platform in the center where the Pump/Reservoir are mounted to is directly above the power supply. With the power supply mounted fan down (as it should be in this case), there is about 25mm of empty space between it, and the bottom of that center platform. Now, you can mount a fan on the top side of that platform if you wish. I personally don't want the ugly backside of my fan showing so I wanted to find a way to mount it up under that platform as an intake fan. Issue is, the standard 120mm-140mm fan thickness is exactly 25mm. So not enough space. Even if you could squeeze one in there, the airflow would be completely choked off being so close to the PSU. What I ended up doing was ordering a slim 15mm thick Arctic brand 120mm PWM fan. It fits under there perfectly with roughly 10mm to spare. They make an all black one and the cables are also black. So it just hides under there completely out of view. It runs very quiet and moves a surprisingly high volume of air! Just that mod alone dropped my case temp by 8c running at around 60%. Second mod, not really a mod, is to now reverse the fan/fans on the back of the case to be intake instead of exhaust. This brings in cool air and blows it across the back of the motherboard and around the sides feeding my 360mm radiator even more cool air. So I have cool air coming in from the bottom and back and heat being exhausted out the right side and top. I did a couple different fan configs and this one drops the temps the most. Mod #3. Fitting the clip in cable cover under the GPU. Out of the box, you have exactly 280mm of GPU space to work with if you intend on using this bottom cover. Any longer and you can simply pull it out and fit longer GPU's. My GPU waterblock is roughly 290mm. What I did was dremel out a rectangular cutout in the center of that cover to allow the longest part of my GPU to pass through it. Fairly easy mod if you of course have the tools. Without that cover it just didn't look right with all of my PSU and cable extensions exposed. I wanted a no compromises, clean build so I did the extra work. NOTE: I am using an EK P360 Radiator which is exactly 39mm thick. Most AIO radiators are about 10mm thinner and have plenty leave plenty of space. With the addition of standard 25mm thick fans, my setup JUST BARLY FITS! No cutting of that center platform needed. There is quite literally 1mm of space left so the fans do not rub. I took a bunch of pics so take a look and hope this info helps!! I absolutely loved building in this case. Fairly easy to cable manage in and very little wasted space. Its a head turner for sure. ... show more

    • beautiful case but challenging build
I absolutely love how my new PC looks, but it was a challenging build. The case does everything it can for you - built-in cable retention clips along the back, easy removable panels, lots of options for mounting SSDs, and just tons of quality features overall. everything feels high quality and the bay window style glass panels are sight to behold. a couple of words of warning though: Radiator Size - I did manage to fit a 420mm radiator in it, but not easily. It's so tight the fan power cables coming out along the bottom of the rad blocked it from being inserted. I had to unclip them from their retention on the back of each fan. also, make sure your radiator is not too thick - I went with Thermal Take brand since I figured it would fit in their case (barely), but I hear the Arctic Freezer 420 won't, due to the thicker rad. Power cable length - Due to the orientation of the board in the case, I had to buy 12v EPS extension cables to reach, because my power supply cables were not long enough. They were also too thick to fit in the cut-out while a radiator was mounted. I found some flat ribbon style extensions which worked out great. Display Cable Angle - getting display cables plugged into the graphics card was a challenge. there's a sharp turn they have to do and my displayport cables were simply too thick to feel comfortable bending that hard. I found some short 90 degree extensions that worked out great. I suppose if you're building in this case, you've probably already watched videos on it and know what you're up against. and if not, go watch some videos first! make sure you're ready for the challenge. It does pay off when fully assembled - there's really nothing else quite like it. ... show more

    • Good case for desk restrained places, has some limitations and mild build quality quirks.
After some finagling, it's working exactly how I wanted. Out of the box, several of the panels were warped to the point I had to carefully and methodically bend them back into place. Without doing this, they wouldn't fasten 100% into the screwless mounts and would always be floating away from the chassis slightly (which was annoying). There is also the frankly baffling decision the designers made to make a single small entrance into the io area of the mobo when there clearly should be 2 areas. I guess it was a cost saving measure but this case is otherwise not cheap. The one entrance makes cable routing a genuine headache. I didn't mind having to lift the fans off every time to access the IO, I knew that before buying the case. But the one hole just seems like a stupid cost saving measure. They should've not included the extra lcd mount and just punched out that hole and it would've made things much better. Tbh because of the one hole, all of my cables feel really tight and constrained, not a great feeling when it's going into a multi thousand dollar computer build. It definitely has enough ventilation for higher end builds. I have a 7800x3d and a 9070xt, I use a noctua nh-d15 cooler and put 3x noctuas on the side for positive pressure cooling. The 9070xt was very slightly throttling in my old tower 100 itx case. It no longer has that issue. Generally, the case is easy to build in, but beyond the io there are 3 areas to be careful with, the 24 pin power needs a pretty extreme bend, I'm using a 180 degree adapter and its working well, without one though its going to block a lot of the air intake from the bottom fan because of how much it has to bend to fit. The same is true with a usb 3.0 header I have, the bend is extreme and probably causing stress on the header and cable. I plan on getting an angled adapter to alleviate that strain. The final area isn't as much of an issue. I thought you could use the AIO mount on the gpu side for extra ventilation. Technically, you can, but my gpu is too fat and cannot fit anything in between. If you used 1-2 slim fans and a 2 slot graphics card, I think it might work. ... show more
