For a 1080p projector up to 10 metres away, the Gizzu 4K HDMI 2.0 10m cable at R129 usually copes, but test 4K at 60Hz first. For a 20 metre run in a Pretoria church or school hall, the PROMATE PROLINK4K60-20M fibre cable at R799 works one way only.
Running an HDMI cable over 10 metres to a projector in a church hall or classroom is where cheap cables start to show their limits. The build that works has three parts: a cable rated for the distance, a tidy route, and a test before anything is mounted. Follow that order and the back row gets a clean picture without a second trip up the ladder.
For a 1080p projector up to about 10 metres from the source, the Gizzu 4K HDMI 2.0 10m cable at R129 is the lowest-priced option at that length, and a 1080p signal needs far less bandwidth than 4K, so copper usually copes. For 4K at 60Hz, copper gets less reliable past about 5 to 7 metres, so bench-test the 10 metre cable first. If it drops out, or the run is 20 metres, the PROMATE PROLINK4K60-20M fibre cable at R799 is the one to use, and it only carries the signal in one direction.
Measure the path the cable will actually take. Start at the laptop or source, follow the wall and the ceiling drop to the projector, and go around any pillar or door frame. Add a metre or two at each end for slack. A projector nine metres from the laptop in a straight line can need a 10 metre cable once the route bends around a pillar.
In a Pretoria church hall, a ceiling-mounted projector adds the drop from the ceiling to the wall plate or the lectern. Count that drop in the total before you order, because a cable that is one metre short is the usual reason for a rushed second purchase.
The Gizzu 4K HDMI 2.0 Cable 10m at R129 supports 4K at 60Hz and up to 18Gbps of bandwidth, with 3D and HDR support, and those are the specs to check against the projector's HDMI input. A standard copper cable is the simplest route, with no power supply or box at either end.
4K at 60Hz over a long copper run gets less reliable past about 5 to 7 metres, so test the run before you mount anything. For longer runs, consider an active or fibre cable. An active copper cable, with a signal booster built into one connector, sits between the two, but this build sticks to standard copper and fibre. The full HDMI cable range shows the lengths on offer, so match the length to the measured route.
The PROMATE PROLINK4K60-20M at R799 is a 20 metre optical fibre cable, rated for 4K at 60Hz and 18Gbps, with gold-plated connectors. It is unidirectional, so plug the laptop into the end the cable is built for, because it will not carry the signal the other way round. It also supports Ethernet for internet sharing, which only matters if the hall has a network point to share.
At R799 it costs more than six times the 10 metre copper cable at R129. Spend that money only when the run is genuinely longer than copper can carry, and not because the bigger number looks safer.
Test the whole chain on a bench first: laptop, cable and projector, with a 1080p test image on screen. Then route the cable along the skirting or through trunking, and never pinch it under a door or behind a wall plate, since pinching can damage the shielding. Label both ends with the source and the projector, and clip the run at regular intervals so it does not sag.
Power the projector on, check the picture from the back of the hall, and only then mount the cable permanently. If the projector itself still needs choosing, the projectors range shows the models on offer.
The Gizzu 4K HDMI 2.0 10m cable at R129 carries a 4K 60Hz signal at 18Gbps. 4K at 60Hz over a long copper run gets less reliable past about 5 to 7 metres, so test the run before the cable is clipped in place, and consider an active or fibre cable for longer runs.
The PROMATE PROLINK4K60-20M at R799 is a 20 metre optical fibre cable rated for 18Gbps. The signal travels as light, which keeps the picture steady across the length where copper starts to lose quality.
Yes. The PROMATE PROLINK4K60-20M is unidirectional, so the source has to plug into the correct end. Route the run with the laptop end marked before you fix it to the wall.
Avoid pinching the cable in a door hinge or behind a wall plate, and keep the bends gentle. Clip it along the skirting or through trunking so it does not sag or get stepped on.
The Gizzu 4K HDMI 2.0 10m cable at R129 is the lowest-priced 10 metre option in this range. It also supports 3D and HDR, so it covers more than a basic run.
The PROMATE PROLINK4K60-20M at R799 handles 4K at 60Hz over 20 metres. Check the hall network before using the Ethernet support, since that feature is only useful if a network point is nearby.

A mid-tower case suits a South African creator PC when the CPU, board, GPU, PSU, RAM and cooling are chosen as one balanced build. The listed Ryzen 5 5500 at R1,100, ASUS Prime B850M-F WiFi at R2,300 and RM850e at R1,900 point to a practical parts mix where power headroom and board features matter as much as the case itself.

A USB microphone can improve voice capture for DaVinci Resolve editing notes, voiceovers and podcast audio, but it does not replace the creator hardware needed for heavy render, AI and large projects. The input mentions creator GPUs from RTX 5070 Ti 16GB R12,700 to RTX PRO 4000 24GB R16,700, so treat the mic as an audio upgrade alongside the workstation decision.

A 2700RPM pump spins its impeller 2700 times a minute to push coolant round the loop. Faster flow moves heat from the CPU block to the radiator, though a quicker pump can be a little louder. The Antec Omni Matrix 360 at R999 pairs it with an ARGB head.
Plug the three pre-connected 120mm fans into one PWM fan header, since they run from a single cable. If the lighting has its own lead, send it to the addressable header, usually labelled ARGB. Evetech's Omni Matrix 360 at R999 follows that same plan.
Compatibility starts with your motherboard socket. The Antec Omni Matrix 360 covers LGA 1851 and LGA 1700 sockets, as well as AM5 and AM4. Confirm the socket name before you open the box, since the mounting hardware differs between platforms.
A PWM fan changes speed on a board signal, while a fixed-speed fan runs at one rate. PWM lets a curve ramp up under load and stay quiet at idle. In a small flat in Durban with a shared lounge, quiet idle curves matter, and the Omni Matrix 360 uses PWM fans.

Yes for clips, trim, mounts and brackets, but never for brakes, steering or seatbelts. A parked car in a South African summer gets hot enough to soften PLA, so PETG from R219 a spool or ABS at R299 is the safer choice for anything that lives inside the cabin.
An extender fixes weak WiFi on a Vuma line only when a room or two sits just past the router's reach. Vuma runs the fibre but your ISP supplies the router, and a R919 TP-Link RE450 suits a small gap, while brick double-storeys need mesh or a cabled access point.
