Perfection. This case is so good. The little touches are what makes it awesome. The complete covering in removable cleanable dust filters. The airflow options and performance. All good stuff.Be advised, if you are using an Arctic Freezer III 360 it is a very thick radiator/fan. You can easily fit that and even longer. But the thickness is where it’s a kicker. This one you literally have 1mm of clearance between the radiator fans and the internal casing that surrounds the power supply. It fits just fine, but you have to plan in advance. This is where the 2x CPU power cables will come through the port hole, right next to the radiator fans, and you have to vent the CPU cables 90 so they don’t touch, basically 90 degrees and out the back side of the mobo. It works great it’s just tight. You need to pass the power cable through then tighten down the mobo to the case. Then also remove the tiny side panel inside that has a thumb screw and holds extra SSDs. It’s an optional panel and not necessary so it’s not an issue. It just doesn’t fit when the thumb screw is there with the radiator.

Been looking for a 300 for a while. The turquoise one came available and i had to get it. I've been building PC's for people for about 20 years now and this is by far one of the easiest to work with and it looks great in the end. This case is amost completely toolless. Every panel is on by a strong magnet yet easy enough to take apart. Plenty of room for fans. This is a M-ATX case that you can easily fit a full size GPU in without ANY issues. The channels on the back for cables keeps it all neat and clean. There is lots of room in the base to tie up additional power cables and it's not seen. You have the option of purchasing a front LED screen for the case that matches the color for about the price of the case which, in my opinion, isn't worth it. I did buy the additional base so that i could side mount my pc which i haven't done yet due to current space. Overall things went in super easy, plenty of space, and looks amazing when done.Con (but not really a con) The Motherboard and GPU are enclosed by the case. Really weird design but not really a flaw. you have to take the top off and run your cables through a channel and attach them internally. The only real con to this is if you want to run wifi antennas that attach directly to your mobo. Mine do not so its not an issue. Not taking a star off for this, it's just a different design that keeps your case super clean.

Install was easy!Huge benefit if you are using a AIO liquid cooler, as you can orient the case to ‘submerge’ the pump. Big plus as the pump cannot cavitate, protecting the CPU and increasing the life of the pump. Highly recommend because of this.

Best one yet if you ask me. Well done for Thermaltake

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.
