If you want to use those fittings, I can cut you a couple of lengths of tubing and mail them to you.
ETA: I just realized we have already had this discussion, so I guess this method is not what you were asking about.
Well, to be honest, I've been so overwhelmed with trying to get everything I need, trying to figure out what to change, what to keep similar, and spending WAY too much time online, I either don't remember or I didn't check back on the thread for a few days and missed it. I was probably mulling over so many options that I didn't know yet, but as everything starts to slowly come together, then it's much easier to make these decisions. I don't want to make a decision on how to setup my SLI based purely on performance, nor do I want to buy all Scratch & Dent stuff, unless it's a screaming deal. I'm so obsessed on getting this thing finished now that I have a new CPU in my hand, but I'm trying to figure out what parts to use where based on performance and aesthetics. I don't want someone looking at my rig that I've put so much time into (too much), and them be like, "that's freaking ugly!" So, I've been suffering a strong case of paralysis through analysis (where you do so much research and analysis on everything that you keep changing your mind, getting confused, and at the end of the day make no decisions.) This has been a headache.
If the offer still stands, YES, I would LOVE to take you up on your offer. I may have mentioned this earlier, I don't remember. Phobya and one other company, I think Koolance, make a nickel, or some other metal, tubing, which already has fittings on each end of the tubing, and the tubing is adjustable. You can shorten it or lengthen it depending on which MB you have and which slots need to be used for your GPUs. Initially, I thought this was the way I was going to go, but as time progressed and I get all my waterblocks installed and have been reading (mostly looking at pictures) about fittings for rigid tubing, I really like the way some of them would look with these Nickel + Plexi waterblocks.
I already ordered some rigid compression fittings (EK-HD), but I ordered them spur of the moment before looking at any other options because I was buying something else and wanted them to include it in the box so I wouldn't have to pay for shipping twice. After looking into these more, I see that even EK offers better fittings. The EK-HDC fittings are supposed to hold the tubing in better, which I probably need. Some of the other brands just look badass. So now I'm sending these back, and I'm looking at other brands of fittings to use with the acrylic tubing for my GPUs. Lots of options again, The Monsoons I really liked, but the Primochill were next. I really like some of them.
One question though, I read about the PETG tubing when reading the entire internet to finish this thing, and one thing I read is that UV lighting can discolor it. Any truth in this? I would love to know how to build a watercooling system with hard line tubing because it looks so much better. Another thing I read is how much easier it is to work with than acrylic......it bends easier, apply less heat, etc. I'd also like to find out when someone says UV light discolors the tubing, does sunlight and UV lighting inside the case have the same effect. I wouldn't think so.
You know what, F*)#K it. If you're still willing to cut some tubing and send it to me? That would be awesome. I'm thinking too much into it, and I'm getting long winded. I wouldn't even be surprised if people see my name, and just skip my post without reading it because they don't have time to read a novel. If the tubing turns yellow by UV light, I'll cross that bridge if I ever get there. For the time being, I would be very greatfull with anything you could help me out with. Since this is my first experience with rigid tubing, I don't know much about the different fittings except they all look better than any standard compression fitting. If anyone was only using rigid tubing for SLI between their GPUs, can't you use any size you want between the GPUs? If you're having a problem with anything just above or just below 1/2", try a 5/8" connection. The relationship between the Imperial system and the Metric system isn't perfect, but as the size goes larger, the delta compresses. For example, 1/2" is technically 12.7mm, not 12, which is a difference of 5.5%. When you look at 5/8", it's advertised a 16mm fitting, but in reality, it's 15.875, which is a difference of 0.78%. So theoretically, that one should fit better.
Please PM me. I'm really interested in the tubing. If you have multiple diameters, I could try out a few more to see what works best, if not, no big deal.
