Your PC belongs on the floor next to your sim rig, ideally on the side of your dominant hand and within about two metres of the wheelbase, pedals and screens. That short distance keeps your USB and display cables reliable, keeps heat and dust away from the PC and keeps the vibration of the frame away from your hardware. Placed behind the seat or under a desk across the room, the same PC often brings USB dropouts, flickering screens and a messy floor.
In this guide you learn how to pick the right spot, how long your cables may be and what changes when you add a direct drive wheelbase, triple screens or bass shakers. The assembly video below shows how the cables run through a SIMGASM Sport frame, which helps you picture the routes before you decide where the PC goes.
Why does PC placement matter for a sim rig?
The spot you pick for your PC decides how stable, quiet and tidy your whole setup feels.
Cable length decides signal quality
A sim rig connects a lot of devices at once: a wheelbase, a steering wheel, pedals, maybe a shifter, a handbrake and a button box. Most of these talk to the PC over USB. Passive USB cables are reliable up to a few metres, but every extra metre and every extension adds risk. The result is a classic sim racing problem: the wheel disconnects in the middle of a race. Display cables are even more sensitive. A high refresh rate monitor on a long DisplayPort or HDMI cable shows black screens or sparkles long before a USB cable gives up.
Heat, dust and vibration
A gaming PC pulls in a lot of air. Put it under a seat on a thick carpet and it breathes in dust and its own warm air. A rig also moves. Direct drive force feedback, braking loads of well over 100 kg on load cell pedals and bass shakers all send vibration into the frame. A PC that stands against the frame feels all of it. Hard drives, loose GPU brackets and side panels do not like that.
Where is the best spot for your PC?
For most home setups one spot works best, and it is closer to the rig than most people think.
Next to the rig on the floor
Place the PC beside the rig, about 20 to 50 cm away from the frame, so it never touches the profiles. Choose the side of your dominant hand, because you reach for the power button, the USB ports and the headset more often than you think. Put it on a small stand or a hard board if your floor is carpeted. This keeps the air intake clear and the case away from floor dust. Leave at least 10 to 15 cm of free space behind the case for the hot air to escape.
The space your setup needs grows a little with this spot, so plan around 40 to 60 cm next to the rig for the PC, the stand and the cables.

Behind the seat or under a desk
Behind the seat sounds tidy, but your cables then run the full length of the rig. A SIMGASM Hobby is 1270 mm long and a Club is 1350 mm long, so the wheelbase cable already uses a big part of its reach before it bends around the seat. Under a desk next to the rig works when the desk stands within about a metre. It is a good option if you share the PC with work or school, as long as the display cables stay short.
What about a PC in another room?
Some racers move the PC to another room to get rid of fan noise. That works, but only with active or fibre optic display cables and powered USB extenders. It costs more and adds one more thing that fails. For a first setup, a quiet case next to the rig is the simpler choice. Our tips for a quiet and clean setup at home help you lower the noise without moving the PC at all.
How long may your sim racing cables be?
Cable length is the hidden limit that decides how far the PC may stand from your rig.
As a simple rule, keep passive USB cables under about 3 metres and passive display cables under about 2 metres for high refresh screens. Measure the real route: up the upright, along the profile, around the seat slider and down to the PC. That route is often twice as long as the straight line. Add a service loop of 20 to 30 cm near every moving part, such as the seat slider and the wheel deck, so nothing pulls tight when you adjust the rig.
Our guide to cable routing with service loops walks you through this step by step. If you still see random disconnects, the sim racing latency checklist shows which USB ports and power settings to check first.

Does your rig type change the best PC spot?
Yes, because the frame decides where your cables run and how much vibration reaches the floor.
Hobby and Club frames
The Hobby uses a 40 x 40 mm main profile and the Club a 40 x 80 mm profile. Neither has integrated cable passthroughs, so you route cables along the outside of the profiles with clips or ties. Here a PC on the wheelbase side keeps the main cables short and out of sight. Johan Akkerman, founder and CEO of SIMGASM, has raced since 2008 and built his very first frame from used gas pipes. He designs every SIMGASM rig to be tested as part of a complete simulator, cables and PC included, because a rig only feels good when the whole setup works.
Sport and Pro frames
The Sport (40 x 120 mm) and the Pro (40 x 160 mm) have integrated cable passthroughs. Your wheelbase, pedal and shifter cables run inside the profile and leave the frame at one point. That makes the PC spot more flexible. You simply place the PC where the cables exit. These frames are also motion ready, and on a motion rig the PC must stand off the platform with extra slack in every cable.

What about power, extension leads and safety?
A full sim setup draws real power, so the socket plan deserves the same care as the PC spot.
A direct drive wheelbase, a gaming PC, one or three screens and a bass shaker amplifier all need a socket. Use one good quality power strip with surge protection, mounted to the frame or the floor next to the PC, and never chain several strips together. Keep the wheelbase power brick off the floor where your feet move, and route its cable away from the pedals. Turn the whole setup off at the strip after a session, so the wheelbase never stays powered while nobody sits in the rig.
SIMGASM B.V. builds its rigs in Wijk bij Duurstede in the Netherlands, and the team tests every cockpit with real hardware attached. That is why each frame leaves room for cable clips, power bricks and a clean path to the PC. Pick the aluminium sim rig that fits your hardware, then plan the PC spot before you tighten the last bolt.
Q&A about PC placement next to a sim rig
These short answers cover the questions racers ask most about where the PC goes.
Can I put my PC on the sim rig itself?
It is better not to. Force feedback, braking and bass shakers shake the frame, and a PC on the rig feels every bump. A stand next to the rig keeps it safe and cool.
Does a console need the same space as a PC?
A PS5 or Xbox is smaller and runs cooler, but the cable rules stay the same. Keep it close to the rig, on a hard surface, with free space around the vents.
Which side of the rig is best for the PC?
Choose the side of your dominant hand or the side where your wheelbase cables exit. Both keep cables short and make the power button easy to reach.
Do I need active cables for triple screens?
Only when the PC stands more than about two metres from the screens. With the PC next to the rig, normal passive cables work fine.
