Quick Answer

For a small-form-factor build the Cooler Master NR200P is the case most Evetech ITX buyers start with, usually R1,800 to R3,500, fitting a 304-330mm GPU in a footprint under 20 litres. Budget R1,800-R2,500 for the NR200P-class staples or R3,000-R4,500 for premium aluminium sandwich cases.

GPU And Cooler Limits Make Or Break An ITX Build

ITX is all about clearances. The Cooler Master NR200P takes a 330mm GPU and a 155mm air cooler, which covers most triple-fan RTX 4070 cards. Sandwich-layout cases like the Lian Li A4-H2O are tighter, around 320mm GPU but often need a 240mm AIO instead of a tall tower. Check the exact GPU length: an RTX 4070 Super runs 300-330mm, so a few millimetres decide whether it fits. Plan cooling before parts, not after.

SFX Power And Riser Cables

Most ITX cases need an SFX or SFX-L power supply, not a full ATX unit. A quality 750W SFX such as the Corsair SF750 (R2,800-R3,500) comfortably feeds an RTX 4070-class card. If the case uses a vertical GPU mount, confirm the included riser is PCIe 4.0 rated; an older PCIe 3.0 riser can cause black screens or crashes with newer cards, so this is a real gotcha. Cable management is tight, so flat or custom-length cables pay off.

Building And Buying In Vanderbijlpark

Evetech is online-first, so Vanderbijlpark buyers order from evetech.co.za and Evetech's national courier delivers to the Vaal Triangle, usually within 1-3 working days. Inspect the box on arrival before signing. Small cases punish poor planning, so build in this order: mount the motherboard and SFX PSU, fit the cooler, then slot the GPU last. Evetech stocks the popular ITX cases and SFX units locally with SA warranty cover. A compact rig suits a desk near NWU Vaal and VUT where space is tight, just keep two intake fans for thermals.

FAQ

Will an RTX 4070 fit in an ITX case?

Yes in cases rated for 320mm-plus GPU clearance, such as the Cooler Master NR200P (330mm). Measure your specific card first; RTX 4070 Super models run 300-330mm, so the few millimetres of margin matter in a sub-20-litre case.

Do I need an SFX power supply for ITX?

Most ITX cases only fit SFX or SFX-L units, not full ATX. A 750W SFX like the Corsair SF750 at R2,800-R3,500 powers an RTX 4070-class build with headroom; check the case spec sheet for the exact PSU form factor.

Why does my ITX GPU crash on a riser cable?

A PCIe 3.0 riser paired with a PCIe 4.0 GPU can cause black screens and crashes. Confirm the case ships a PCIe 4.0 riser, or set the slot to PCIe 3.0 in BIOS as a workaround until you fit a rated cable.

TIP

length, cooler height and PCIe 4.0 riser support against your exact parts before buying an ITX case, then fit two intake fans for cooler load temps.
