The claim: pay for airflow, not LCDs
The pitch is simple. A case with an LCD panel and ten RGB fans costs more, and its extra cost doesn't automatically buy better cooling or upgrade room. BGR points to cases under $100 that, in many instances, offer better airflow and upgrade room than pricier, flashier ones. It names three: the NZXT H5 Flow, the Lian Li LANCOOL 207 and the Corsair Frame 4000D RS.
It then says an extra $100 to $200 does little for a GPU but goes a long way on a CPU, motherboard, RAM or cooler. It also suggests peripherals, such as a mouse, keyboard or headset.
Its examples:
- A Ryzen 7 9700X against a 9800X3D.
- A single 8GB DDR5 stick against a dual-channel kit with double the memory.
- A Gigabyte B650 board against a B850 board with Wi-Fi 7, a PCIe 5.0 x16 slot and DDR5-8200 support.
- A 360mm AIO cooler in the $85–$100 range.
The prices in the article are snapshots and sale prices "at the time of writing." Treat them as a starting point and check current prices before you buy. That matters more now that BGR says memory prices are at new highs.
What independent testing says
GamersNexus has tested two of the three cases extensively, so here is what it found.
Lian Li LANCOOL 207
GamersNexus's 2025 roundup gave the 207 its Best Sub-$100 Case award for a second year. The reasons were its thermal performance and its aggressive pricing. In the original review, the original MSRP was $80, and the review said the 207 landed among the cheapest cases on the outlet's charts.
In noise-normalized testing, case fans were adjusted until the case measured 27 dBA at one meter. In that test:
- The CPU ran tied for chart leader in CPU thermals.
- Average CPU temperature was 41°C above ambient across all cores and 44°C on the P-cores.
- The GPU averaged 42°C above ambient, with memory at 47°C and hotspot at 55°C.
These are figures from one outlet's test rig and method. Your own parts and room will give different numbers.
The 207 achieves this by moving the power supply to the front of the case. That lets two bottom intake fans feed the GPU directly. It also creates the case's main problem.
GamersNexus said the side panel can be hard to close with cable-heavy builds or thick, individually sleeved cables. Its advice:
- Choose a 150mm-deep PSU rather than the 160mm maximum.
- Use a modular PSU.
- Prefer slim, flat cables.
It gave the case a strong, but caveated recommendation, with the caveat aimed especially at less experienced builders.
Other reviewers were less bothered. TechPowerUp installed a 750W, 160mm PSU and reported it fit with room for the modular connectors. OverClock3D praised the case's cable management. Fit depends on which PSU and cables you use, so check your PSU's length and cable style before you commit.
Corsair Frame 4000D RS
GamersNexus's review explains the SKUs, and they matter when you compare prices:
- The base Frame 4000D was $95 with no fans.
- A $100 RS version has three fans without ARGB.
- A $110 RS ARGB version has three ARGB fans.
The reviewer used three RS120 ARGB fans on the base sample. Corsair's specs say these match the regular RS120, so the results also represent the non-ARGB RS version.
In the same 27 dBA test, the Frame 4000D averaged 43°C above ambient on the CPU across all cores, or 47°C on the P-cores. The GPU averaged 45°C, with memory at 49°C and hotspot at 59°C. That is a big improvement over the older 4000D Airflow, but GamersNexus attributes part of it to the newer case having three fans rather than two. It still called the 207 "the budget case to beat." In the roundup, it named the Frame 4000D RS ARGB its Best Mid-Range Case, partly for its modularity and build quality.
The NZXT H5 Flow, the third recommendation, wasn't covered by the supplied testing. GamersNexus's review text says the 2024 H5 Flow performed similarly well to the Frame 4000D in noise-normalized testing, which is the only comparison available here.
Where the argument needs care
Nothing in the testing shows that LCD screens or RGB fans hurt cooling. It shows that cheaper cases can cool very well. "Best" depends on your priorities. In the same roundup, GamersNexus gave its Best Overall award to the Fractal Meshify 3 and its noise-normalized CPU thermals award to the Meshify 3 Ambience Pro RGB. It named other cases as winners for other categories. A premium case can also bring build quality, modularity or looks that matter to you.
The spending advice is BGR's opinion, not a benchmark result. Whether $100 goes further on a CPU, RAM or a motherboard depends on what you do with the PC. For example:
- Dual-channel memory is a sound upgrade for most gaming PCs.
- A newer motherboard only pays off if you use its extra features, such as Wi-Fi 7 or a PCIe 5.0 slot.
- An AIO cooler helps if your CPU runs hot enough to throttle.
- A $180 mouse is a preference, not a performance necessity.
A short checklist before you reallocate the budget
- Confirm the case supports your motherboard size, GPU length and cooler height.
- Check which SKU you are buying and whether it includes fans.
- For the 207, check your PSU depth and cable type.
- Verify any radiator or AIO support you plan to use. GamersNexus said Lian Li claims formal radiator support only at the top of the 207.
- Compare current street prices, since stock and sales change.
Bottom line: the case is part of your cooling system as well as your build's looks. Buy for airflow and fit first, and spend the savings where your own workload benefits most.
