FOIFKIN F300 Mid-Tower ATX PC Case Budget UK Review (2026) - Build Tested

Think about how many times you'll open your PC case over its lifetime. Swapping a GPU, adding storage, re-routing cables after you've had enough of the mess, maybe just cleaning the dust filters. The case isn't just a box you forget about once the build is done. It's something you interact with constantly, and if it's a pain to work in, you'll feel that every single time. I've built in everything from a tenner-over-budget Fractal to a proper premium Lian Li, and the difference in experience is night and day. So when a budget mid-tower ATX PC case lands on my bench, I don't just want to know if it looks decent. I want to know if it'll make my life easier or harder.

The FOIFKIN F300 is a mid-tower ATX PC case budget UK buyers will find sitting in a very competitive price bracket. It's going up against some genuinely solid competition from brands that have been doing this for years. FOIFKIN isn't a name most UK builders will recognise immediately, which is fair enough. But unknown brand doesn't automatically mean bad product, and I've been surprised before. I spent about a month with this case, built a full system inside it, and lived with it on my desk. Here's what I actually found.

The F300 ships with four non-RGB fans, a mesh front panel, Type-C on the front I/O, and claims to support 360mm radiators. On paper, that's a strong spec sheet for the money. Whether it delivers in practice is a different question entirely.

Fan support is where the F300 tries to punch above its weight. You get mounting positions for up to 360mm radiators at the front, 240mm at the top, and a single 120mm at the rear. The case ships with four 120mm fans included, which is genuinely good value at this price. Most budget cases give you one or two fans and call it a day. The front panel is mesh, which is the right call for airflow, and there are dust filters on the bottom and front. The side panel is tempered glass, and the PSU shroud covers the bottom chamber neatly.

Drive bay support includes two 3.5-inch bays and two 2.5-inch dedicated mounts, which is adequate for most modern builds. You're not going to be running a NAS from this thing, but for a gaming PC with an SSD and maybe a spinner for bulk storage, it covers the bases. The front I/O includes USB 3.0 Type-A ports, a USB 3.1 Type-C port, and combined audio/mic jack. No RGB controller hub, no fan speed controller, just the basics. Which is fine, honestly.

The footprint is slightly smaller than something like the Fractal Design Pop Air, which runs a bit wider, but comparable to the Corsair 4000D Airflow in terms of desk real estate. For most UK home setups where desk space is at a premium, the F300 won't cause any arguments. The tempered glass side panel swings open on a hinge rather than sliding off, which I actually prefer. Sliding panels can feel fiddly, especially when you're trying to hold a component in one hand.

One thing worth noting about the physical design: the front panel has a fairly aggressive mesh pattern that covers most of the face. This is genuinely good for airflow, but it does mean the aesthetic is very much function-first. If you want something that looks sleek and minimal from the front, this probably isn't it. But if you're building a system where thermals matter more than aesthetics, the open mesh design is exactly what you want. The top panel also has a mesh section with a magnetic dust filter, which is a nice touch at this price.

The motherboard tray has a large CPU backplate cutout, which is essential for installing aftermarket coolers without pulling the entire board out. The cutout is generously sized at roughly 150mm x 150mm, so it'll accommodate most cooler mounting systems including the larger AMD AM5 and Intel LGA1700 backplates. This is one of those details that separates a case designed by people who actually build PCs from one designed purely to hit a price point.

Cable pass-through grommets are positioned sensibly around the motherboard tray. The 24-pin ATX power connector grommet sits to the right of the board, the CPU power grommets are at the top, and there are additional openings for front panel headers and USB connections. The grommets themselves are rubber, which is a nice touch. Some budget cases just leave bare holes, and bare metal edges on cable pass-throughs are one of my genuine pet peeves. Nothing like slicing your hand on a sharp edge while routing cables.

There's no vertical GPU mount option on the F300, which isn't surprising at this price. Vertical mounts require a PCIe riser cable and a specific bracket design, and adding that to a budget case would push the cost up considerably. If showing off your GPU through the side panel is important to you, you'll need to look elsewhere or buy a third-party riser kit and hope the bracket spacing works out. For most builders, horizontal mounting is fine and actually better for thermals anyway, since the GPU fans can draw air from below rather than pulling it off the side panel.

The PCIe slot covers are tool-free on removal, which is good. They're the punch-out style rather than proper reusable covers, which is less good. Once they're out, they're out. This is a cost-cutting measure that's common at this price tier, but it does mean if you ever remove an expansion card and want to cover the slot again, you'll need to source a replacement cover. Not a dealbreaker, but worth knowing. The PCIe standard allows for up to seven expansion slots in a standard ATX configuration, and the F300 covers all seven positions.

AIO radiator support is actually one of the stronger points of the F300. The front panel accommodates 120mm, 240mm, and 360mm radiators, the top supports 120mm and 240mm, and the rear takes a single 120mm. That's a solid spread of options. I ran a 240mm AIO at the top during testing and it installed without any fuss. The mounting holes lined up correctly, and there was enough clearance between the radiator and the top of the motherboard that tall RAM wasn't an issue. If you're planning a 360mm front-mounted AIO, just double-check your GPU length as mentioned above.

One thing I noticed during the AIO install: the top panel mesh filter is magnetic and lifts off cleanly, which makes radiator installation much less annoying than cases where you have to remove screws to get the filter off. Small detail, big difference when you're lying on your back trying to hold a radiator in place with one hand and drive screws with the other. The pump head clearance from the motherboard is also fine, even with a relatively large pump block. No issues there.

The two 2.5-inch mounts are on the back of the motherboard tray, which is the modern approach and I like it. It keeps the main chamber tidy and means your SSDs are out of sight behind the tray. They secure with two screws each and the mounting points are solid. No flex, no wobble. For an NVMe-first build, you probably won't even use these bays, but they're there if you need them. Worth noting that M.2 slots are on your motherboard rather than the case, so the F300's storage options are purely for SATA drives.

If you're coming from an older build with multiple HDDs, two 3.5-inch bays might feel limiting. But for a modern gaming PC, it's genuinely enough. Most people are running one or two NVMe drives and maybe a single HDD for game storage. The F300 covers that configuration without any issues. If you need more than two spinning drives, this isn't the case for you, but then again, a budget mid-tower probably isn't the right starting point for a storage-heavy build anyway.

There are Velcro cable tie points along the back of the tray, which is something I always appreciate. Zip ties are fine, but Velcro means you can undo and redo your cable routing without cutting anything. The tie points are in sensible positions: one near the top for the CPU power cable, a couple in the middle for the main bundle, and one near the bottom for PSU cables. It's not as many as you'd get in a premium case, but it's enough to get a clean result if you take your time.

The 24-pin ATX cable has a dedicated routing channel that keeps it separate from the rest of the cables, which is a nice touch. The CPU power cable routing from the top-left of the board to the top grommet is straightforward, and there's enough slack in the channel to accommodate modular cables from most ATX PSUs. I used a mid-range modular PSU during testing and had no issues. If you're using a non-modular PSU, expect to spend more time managing the excess cable bulk behind the tray. It's doable, but it'll test your patience.

The fans themselves are basic. They're not PWM, they're 3-pin DC fans, and they're not going to win any awards for noise levels at full speed. But they move air, they're quiet enough at the speeds a typical system will run them, and having four of them means you're not immediately reaching for your wallet to buy additional fans after unboxing. I ran the system through a month of gaming sessions and productivity work, and temperatures were consistently reasonable. CPU package temps under load sat in the mid-70s Celsius with a 240mm AIO, and GPU temps were in the low-to-mid 70s with a reference-style cooler. Not exceptional, but solid for a budget case.

The dust filters on the front and bottom are removable and washable, which matters for long-term maintenance. The bottom filter slides out from the front, which is the right design choice since it means you don't have to move the case to clean it. The front filter pulls off with the front panel, which is also easy enough. I did notice the front panel clips are a bit stiff initially, but they loosened up after a few removals. The top mesh has a magnetic filter as mentioned earlier. No filter on the rear exhaust, which is standard practice since exhaust fans push air out rather than drawing dust in.

The USB Type-C port is the headline feature here and it's genuinely useful. More and more peripherals and devices use Type-C, and having it on the front panel means you're not fishing around the back of the case every time you want to charge something or transfer files. The internal connector is a standard USB 3.1 Gen 1 Type-C header, so you'll need a motherboard with that header to use it. Most modern ATX boards have one, but worth checking if you're using an older board.

The audio jack is a combined TRRS connector, which works fine with headsets that use a single plug. If you're using separate headphone and microphone cables, you'll need a splitter adapter. This is a common cost-cutting measure on budget cases and it's not a big deal for most people, but it's worth knowing. The audio quality through the front jack was acceptable during testing, no obvious interference or noise. The reset button is small and recessed slightly, which is the right call. You don't want to accidentally hit reset when you're reaching for the power button in the dark.

Panel alignment was good out of the box. The tempered glass panel lined up with the chassis without any gaps or misalignment, and the rear panel (which is solid steel) sat flush. The front panel clips, as mentioned, are a bit stiff, but that's preferable to panels that fall off when you look at them. The screw quality is adequate. Nothing stripped during the build, and the thumbscrews for the rear panel and drive cage turned smoothly. I've had budget cases where the thumbscrews were so poorly made they started stripping on first use. Not an issue here.

Sharp edges. This is the thing I always check on budget cases because it's where corners get cut most visibly. I'm happy to report the F300 is mostly fine. The motherboard tray edges are rolled, the drive bay openings are smooth, and the cable routing holes have rubber grommets. The one area where I found a slightly rough edge was around one of the PCIe slot openings, nothing that drew blood, but enough that I'd recommend running your hand carefully around any edges before reaching in. Overall though, for the price, the build quality is better than I expected from an unfamiliar brand.

The Fractal Design Focus 2 is a genuinely excellent budget case. It has better build quality overall, with slightly thicker steel and better panel alignment consistency. The cable management is also a step up, with more tie points and better routing channels. But it typically costs more than the F300, and it ships with fewer fans. If you're on a tight budget and don't want to buy additional fans, the F300's four-fan bundle is a real advantage. The Corsair 4000D Airflow is a step above both in terms of build quality and cable management, but it's also priced noticeably higher. It's a different tier of product really, and comparing them directly is a bit unfair to both.

Where the F300 genuinely wins is value density. Four fans included, Type-C on the front I/O, 360mm radiator support, and a mesh front panel at a budget price point is a strong package. The compromises are in build quality consistency and the non-PWM fans, but for a first build or a budget gaming rig, those are acceptable trade-offs. If you're an experienced builder who's going to swap the fans out anyway and wants the best possible cable management, spend more and get the Fractal or Corsair. If you want the most hardware for your money right now, the F300 makes a strong case for itself.

The compromises are real but manageable. The 0.6mm steel is thinner than premium cases. The rear cable clearance of 20-22mm is workable but tight. The fans are 3-pin DC rather than PWM, so you have less granular speed control. The PCIe slot covers are punch-out style. None of these things will ruin your build, but they're the signs of where the cost savings happened. If you're an enthusiast who wants the best possible build experience and has the budget to match, the Fractal Focus 2 or Corsair 4000D Airflow are worth the extra spend. But if you're building on a tight budget and want the most hardware for your money, the F300 delivers a genuinely solid package.

After a month of use, the case has held up well. No panel alignment issues developing over time, no rattles from the fans, no dust filter problems. The tempered glass is still scratch-free. For a first build, a budget gaming rig, or a secondary system, the F300 earns a recommendation. It's not perfect, but it's honest about what it is, and at this price, that's enough.
