Hi all,

I recently got a Corsair carbide 200r case for my PC. The case is great but when I ordered it I didn’t realize the top was an open mesh cover. Because of how my desk is set up if I were to spill a drink on my desk it would likely go right into my case and ruin my PC so I am really concerned that I might break my computer. So, I’ve decided to move it to a different corner of my room that would require about 15 -20 feet of Dvi-d cables (for my monitor), 15 -20 feet of USB cable (for mouse/keyboard) and 15 -20 feet of speaker wire.

My question is would the signal of the Dvi-d or USB cables lose signals at that length? I am most concerned about the USB to the mouse/keyboard since I mainly using the PC for gaming so obviously don’t want any signal loss. I read I could get cables with signal boosters, would that be necessary or even helpful at that length?

Also, somewhat of a tangent: is anyone aware of a top cover that would fit on top of the corsair carbide? I like having the extra ventilation but if there was something to protect against water or other liquid spilling into the top of the case I’d be interested.

Thanks!

Yes, you need to be concerned with signal degradation at 15 - 20 feet. That is beyond the limit of the USB specification, so while you may be able to purchase a cable that is the required length, don't be surprised if it doesn't bear the official USB logo. If you need to go that far, get a USB cable that has the active signal booster.

Video is in a similar boat. While you don't necessarily need to get a signal booster for that length, there is no error correction on DVI signaling (including HDMI), so if you get a cheap cable you will get signal drop-out or corruption.

Do not run any of your cables past power strips, wall transformers, electrical service panels, or other areas of high interference, for best results.

I usually buy my high quality cabling from this outfit. They have pretty reasonable prices:
