a cutout shaped to contour the peripheral-facing end and through which a portion of the pass-through connector protrudes; and
power and sideband distribution circuitry.
2. The apparatus of claim 1 , wherein a routing of the first set of signal conductors directly mates a first portion of the peripheral device receptacle to a first portion of the cabling connector receptacle.

a fifth set of signal conductors configured for power and sideband signal transmission,
wherein a routing of the fifth set of signal conductors indirectly mates the second and third sets of signal conductors at the cable-facing end.
6. The apparatus of claim 1 , wherein a routing of the first set of signal conductors directly mates a first portion of the peripheral device receptacle to the cabling connector receptacle in entirety.
7. The apparatus of claim 6 , further comprising:

a second set of signal conductors configured for fabric signal transmission; and
a cabling connector configured to mate with the cabling connector receptacle and to terminate the second set of signal conductors at an end of the fabric signals cable,
wherein the second set of signal conductors directly mates to the first set of signal conductors at the cable-facing end.
8. The apparatus of claim 1 , wherein the pass-through connector, further comprises:
a second set of signal conductors configured for power and sideband signal transmission,
wherein a routing of the second set of signal conductors indirectly mates a second portion of the peripheral device receptacle to the power and sideband distribution circuitry.
9. The apparatus of claim 1 , wherein a routing of the first set of signal conductors indirectly mates a first portion of the peripheral device receptacle to the cabling connector receptacle in entirety.
10. The apparatus of claim 9 , wherein the pass-through connector, further comprises:
a second set of signal conductors configured for the power and sideband signal transmission,
wherein a routing of the second set of signal conductors directly mates a second portion of the peripheral device receptacle to power and sideband distribution circuitry.
11. The apparatus of claim 9 , further comprising:
a fabric signals cable, comprising:
a second set of signal conductors configured for fabric signal transmission; and
a cabling connector configured to mate with the cabling connector receptacle and to terminate the second set of signal conductors at an end of the fabric signals cable,
wherein the second set of signal conductors directly mates to the first set of signal conductors at the cable-facing end.
12. A computing system, comprising:
an apparatus for direct cabled connections of fabric signals, and comprising:
a pass-through connector, comprising:
a peripheral-facing end comprising a peripheral device receptacle;
a cable-facing end disposed opposite the peripheral-facing end and comprising a first cabling connector receptacle;
a first set of signal conductors operatively connecting the peripheral device receptacle and the cable connector receptacle, and configured for fabric signal transmission; and an interconnection board, comprising:
a cutout shaped to contour one selected from a group consisting of the peripheral-facing end and the cable-facing end, and through which a portion of the pass-through connector protrudes; and
power and sideband distribution circuitry.
13. The computing system of claim 12 , wherein the apparatus, further comprises:
a fabric signals cable, comprising:
a second set of signal conductors configured for fabric signal transmission; and
a first cabling connector configured to mate with the cabling connector receptacle and to terminate the second set of signal conductors at an end of the fabric signals cable,
