I am confronted with routing 26 cables so far, not counting the main power supply cable, though this PC Case (MSI Prospect 700R)

Cables are coming from the case itself/display and cables coming from power supply (MSI MEG Ai1300P PCIE5).

Some of these cables have to be routed to the motherboard (ASRock B650E Steel Legend WiFi)

So far the easy ones were the CPU power cables, those I managed to do via the back right duct.

But what about the rest ? I could use some help here and maybe some visual drawings or ideas how to route these cables best...

The 600 watt graphics card cable should probably go "over" the graphics card so it's out of the way of the ventilators.

I am also struggling with the concept of the "cable shroud" and especially struggling with where to put the sata cable plugs/connectors.

Anyway here is a list of cables that need to be routed, give me your best ideas if possible, I will also try and find some ideas on youtube ! ;)

One thing I kinda fear/run into is the cables blocking the harddisk bay. It would be very nice if a routing plan could keep that area free.

In that regards I have a question: Is it possible to move the harddisk bay to the front of the PC case to create more room near the power supply so that sata connectors could be maybe hidden there instead of in the front where they might be near the in take ventilator blades...

Cable 1: The power supply main power cable.

Cable 2: CPU Power Cable 1 (ATX 12 Volt 1)

Cable 3: CPU Power Cable 2 (ATX 12 Volt 2)
(I am going to plug in a second cpu power cable just in case, supposedly it can't hurt/cause damage but it should
give if extra power if the CPU needs it, I believe there might be rare cases where the CPU might spike and need some additional juicy/power.
So it's good to give it some extra).

Cable 4: CPU Cooler Ventilator Power Cable (CPU Fan 1)

Cable 5: Main motherboard power cable (ATXPWR1)

Cable 6: Connect USB 3.2 Gen 2x2 Type-C from PC Case to the Steel Legend motherboard: Port 12 Front Panel Type C USB 3.2 Gen2x2 Header (USB32_TC_2)

Cable 7: Connect USB 3.2 Gen 1 Type-A from PC Case to the motherboard: Port 11 USB 3.2 Gen1 Header (USB32_8_9)

(6 pin power cable split into 4 sata power cables)
Cable 8: Harddisk 1 Power Cable, Connect from Power supply to Harddisk in disk bay.

Cable 9: Harddisk 2 Power Cable, Connect from Power supply to Harddisk in disk bay.

Cable 10: Harddisk 1 Data Cable (SATA), Connect from Harddisk to Motherboard Port 15 (Sata 1)

Cable 11: Harddisk 2 Data Cable (SATA), Connect from Harddisk to Motherboard Port 14 (Sata 2)

(I hope they don't cross, don't know yet, otherwwise maybe hd1 to port 14, and hd2 to port 15 (swapped))

(6 power power cable split into 4 sata power cables, use separate SATA power cable to power supply to be on the safe side !)
Cable 12: PC Case Ventilators and Lights and Display Panel Control Board SATA Power Cable connect it to Power Supply Sata Power Cable.

Cable 13: PC Case HD audio connect to motherboard port 29 Front Panel Audio Header (HD_AUDIO1)

Cable 14: PC Case Ventilator (4 pin connector)cable (from controller board?) connect to port 25 Chassis/Water Pump Fan Connector (CHA_FAN1/WP)

Cable 15 and 16 united together: PC Case Power SW (switch) and Reset SW (switch) connect to port 17 System Panel Header (PANEL1)

Cable 17: PC Case ARGB lights cable connect to motherboard port 27 Addressable LED Header (ADDR_LED1)

Cable 18: PC Case Double cable connected USB cable connect to motherboard port 22 USB 2.0 Header (USB_3_4)

Cable 19: PC Case sensor cable (put it anywhere you like, maybe just hang it in the pc case to measure temperature in the PC case but then it's dangling and
it could maybe end up in a ventilator, however I say "techgaming" youtube channel put/attach it to the back of the motherboard tray, basically
back of cpu to measure it's temperature)

Cable 20: Power Supply G.I. (Gaming Intelligence) Connector connect with special Mini USB to 9-Pin Cable connect to USB 2.0 motherboard port: 22 USB 2..0 Header (USB_3_4)

Cable 21: Graphics Card connect the 600 watt power cable to 600 watt power cable from power supply to graphics card. MAKE SURE TO PLUG IT WELL OR YOUR PC WILL CATCH FIRE.

Cable 22: Extra PC Case Ventilator 1/Front power cable connect to PC motherboard (port 16 Chassis/Water Pump Fan Connector (CHA_FAN4/WP))

Cable 23: Extra PC Case Ventilator 2/Middle power cable connect to PC case FAN Controller Board (power socket)

Cable 24: Extra PC Case Ventilator 3/Back power cable connect to PC case FAN Controllor Board (power socket)

Cable 25: Extra PC Case Ventilator ARGB connect to PC Case FAN Controller Board.

Cable 26: Extra PC Case Ventilator ARGB connect/daisy chain to PC Case Ventilator 1 ARGB connector (can be done in multiple ways be carefull).

Bye for now,
Skybuck.

Cable 27: Extra PC Case Ventilator ARGB connect/daisy chain to PC Case Ventilator 2 ARGB connector

(optionally could be attached to different port of fan controller for seperated color settings).
I'm thinking of maybe making some pictures and drawing some lines or something :)

Bye for now,
Skybuck.

I found one example where this person literally routes everything through the main duct and side duct, seems a bit crowded/explosive ! ;)

I probably have a bit more cables and thicker cables and sata plugs... hmmm...

I was thinking of using the room on the left side of the picture... "cable shroud".

Bye for now,
Skybuck.

I found another one, this one is very interesting, it shows the harddisk bay in the front, apperently it may be possible to move it ?!?

https://www.razorman.net/reviewshardware/wp-content/uploads/MSI-MEG-PROSPECT-700R-48.webp

This seems much more ideal, now the harddisks get direct airflow, hopefully not charging anything with electricity... I used direct airflow on harddisks in the antec 1200, it never was a problem, so neither should this be a problem, this would open up a whole lot of space behind the power supply and also keep the harddisks bay nice/clean accessible ! Hmmm...

I don't think anything was mentioned in the manual about this possibility, or I may have overlooked it... hmmm...
Bye for now,
Skybuck.

Meanwhile I have discovered some things:

1. The harddisk bay can indeed be moved to the left and re-attached but it was very difficult to do, see other thread below for tips how to do it properly:

https://forum-en.msi.com/index.php?threads/msi-prospect-700r-harddisk-bay-can-be-removed-place-elsewhere-solved.390062/

2. The large black shroud has "invisible/secret holes" in the back, which give access to the back of the PC Case/back of motherboard tray, near the power supply.

If moving the harddisk bay to the front it becomes a lot easier to route cables upward through these secret holes at the top of the black shroud, which will feel like bottom exits/entries on the back. Now it kinda makes sense why there is this big DUCT running across the back... it's probably possible to route some of the USB cables and reset switches and such through this duct, towards the power supply and then up the black shroud invisible/secret holes... to directly/shortly connect to the motherboard.

The most left/near back of PC case shroud hole/invisible port is "blocked" by the power supply, so it cannot be used, by the middle one as well as the right one can be used, especially the right one can be used if the harddisk bay is moved to the front, this could be a major advantage to moving the harddisk bay to the front side.

So there is more to it, than just meets the eye at first glance.

Ofcours I have seen builds like this, which have these "magic" holes on the bottom lol... in all the darkness/blackness of this case it's kinda easy to forget or miss it, but one just has to take the time for it, observe the case, take it easy, and take it all in and find ways to do what you want...

MSI is doing a poor job so far of selling this case properly, but not showing this properly in videos, then again there was this long video, but it was this kinda annoying guy trying to build two systems at the same time... way to confusing for the average buyer.

Just build one system well, do it well, document it well and more people will buy this case because so far I think it's pretty awesome, but time will tell ! ;)
