Physical configuration of computer system
A physical configuration of a computer system is described. The motherboard has a first series of I/O ports at an edge thereof. A riser card is perpendicularly connected with the motherboard, wherein the riser card has a second series of I/O ports at an edge thereof. A housing encloses the motherboard and the riser card, wherein the housing has a plurality of openings, exposing each of the first series of I/O ports and the second series of I/O ports so as to form an L-shaped I/O port area on a flat surface thereof.
1. A computer system having a physical configuration comprising:
a motherboard, having a first series of I/O ports at an edge thereof;
a riser card, perpendicularly connected with the motherboard, wherein the riser card has a second series of I/O ports at an edge thereof;
a fan module, electrically connected with the motherboard;
a main housing;
a side housing assembled to the main housing so as to form a unitary housing, enclosing the motherboard and the riser card,
wherein the side housing has a concave portion to accommodate the fan module;
wherein the side housing has a plurality of openings, exposing each of the first series of I/O ports and the second series of I/O ports so as to form an L-shaped I/O port area around the concave portion on a flat surface thereof.
2. The computer system of claim 1 , further comprising a fan control board perpendicularly connected with the motherboard for electrically interconnecting the motherboard and the fan module.
3. The computer system of claim 2 , wherein the concave portion comprises another opening to expose a connection port of the fan control board such that the fan module is detachably connected with the connection port.
4. The computer system of claim 1 , further comprising an expansion card enclosed within the unitary housing, wherein the expansion card is perpendicularly connected with the riser card, and has a third series of I/O ports at an edge thereof.
5. The computer system of claim 4 , wherein the plurality of openings further exposes each of the third series of I/O ports.
6. The computer system of claim 1 , wherein the motherboard is secured to and in parallel with an inner flat surface of the main housing.
7. The computer system of claim 6 , wherein the riser card is secured to and in parallel with another inner flat surface of the main housing.
8. The computer system of claim 1 , wherein the concave portion comprises a plurality of ventilation holes, allowing airflows generated by the fan module circulation to be circulated.
9. The computer system of claim 1 , wherein the riser card substantially abuts on the motherboard.
10. The computer system of claim 9 , wherein the expansion card substantially abuts on the riser card.
