They still have 5.25 bay reservoirs with pumps...but most will be with a D5 or DDC pump. I use the EK D5 D-Bay reservoirs and have used Alphacool 5.25 DDC pump reservoir also as well as XSPCs version from a while back.
Have you any personal experience with that? And if so, are you willing to share? I've read.. "reviews".. but if you've used it, i'd like to read what you thought of it.
I did a couple of loops for others with it a couple (maybe "few") years ago. To my knowledge, both are still working with no issue. They were easy to work with, small enough for good flexibility in mounting, and moved enough liquid for a small loop without a lot of restriction (they are easy to run in serial should you need more). They were quiet enough, but a little buzzy sounding at times, but it was masked by them being in the case. I never did any flow rate or head pressure testing, so I can't be of help there. Just impressions, no numbers.
Yeah....the little girl hentai avatar is really creeping me out....
