I have a single rack 11/45 system with one RK05 on top, then a RL02, a
RK02 and then the CPU. All controller cards are in the CPU box itself, the
RK11-D has its own backplane and fits into the CPU box, and there's an
additional 4-slot DD11. In total, I have the CPU boards including FPP, two
DL11-W cards (one for the console, one for auxiliary stuff), a 128kW MOS
memory board, the RL11 controller (hex board), the RX211 controller (quad
board) and the RX11-D controller at the end (with terminator card on the
Unibus out slot). There's still space for another 4-slot backplane in the
box. And all the stuff runs happily together and consumes only about 1300
watts (it's standard to have 230V outlets with 16A fusing here, a washing
machines takes 2000W and the condensing dryer over 3000W).
BTW I run RT11 or 2.9BSD on a RK05 disk. Yes, I have a small single RK05
disk 2.9BSD system (including a 256kB swap space!) with stuff like kermit
etc. which I mainly use for playing around or data transfers. I think
there's even the compiler on the disk.

I have an
H-960 spare. I was REALLY hoping to make the 11/45 a single bay
setup, but it doesn't seem that is really possible. I'll have to hunt up a
Why not? In one of my H960s, I have the 11/45 CPU with it's PSUs (bottom
3 bays). Then an RX02 -- that doesn't obstruct the cooling to the CPU
from what I've found. Then an RK05, but you could put an RL there. On top
is the RK11-C controller at the front and its H720 PSU at the back.
