Hi Sacguy71,
Oh come on, you just spent a small fortune on cases and modules and then 20 bucks a year for creating bigger racks here would top your budget? ;-) With that Unicorn account you are supporting this website too :-) No, I am not one of the owners of this website, just supporting them by trying to convince you ;-)
Regarding your 1 U modules question. I almost bought last year two Intellijel 7U cases and put quite some efforts in checking those 1U modules, check out my rack-planning for that double-Intellijel 7U case, those 1U modules might be interesting to consider. I put the whole plan on hold so I didn't continue this rack planning but for the 1U modules it might be interesting. Meanwhile a few new 1U modules have been released I noticed, so check out the 1U modules that had been released this year by Intellijel.
Once you got the MDLR case please let me know your impression after a few days of use, looks like a great case!
Have fun with it and please keep us updated, kind regards, Garfield.
