Doepfer A-100 LC9 is probably the most popular case for entrance to the eurorack world, and there's a good reason for that: it's affordable, and it's reliable. The power supply PSU3 replaced the older PSU2; this one is more reliable, provides more overall amperage for modules and is compatible with modules that need +5V power rail without the need for an adapter.
Even if this is LC9 (low cost unit), finish is done quite well: power rails are sturdy, screw rails are not misaligned and wooden casing is firm. Wood is not painted or even lacquered. It's a pity there are no rubber legs on the bottom and some indentation on the top; some people will miss a handle too. I guess you can't have everything.
My only complaint is grounding issue; if I plug my headphones directly in a mixer cranked up to the maximum, sometimes I can hear very faint leakage from one of my oscillators. On normal levels this won't affect the sound. And if wider experienced community is to be trusted, it shouldn't stop you from interconnecting two or more cases. It's still advisable to do some extra grounding as it will increase the longevity of your case.
LC9 is the best option for starters and the most affordable price-per-size unit. There is simply nothing else quite comparable on the worldwide market. I will certainly get one more.
(The power supply will work anywhere in the world; Thomann sends extra cable with plug (rather than a cheap adapter) that fits your local power outlet if you are not in continental Europe.)
