Abstract
Abstract A modular computer chassis comprises a main chassis to which a motherboard is attached and a subchassis attachable to the main chassis. The subchassis is capable of having at least one computer component attached thereto such that the computer component is electrically connected to the motherboard. The computer component is thus separable from the main chassis by removing the subchassis from the main chassis. The subchassis contains those computer components subject to mechanical wear and most often requiring replacement, i.e. the power supply and disk drives. The subchassis is mechanically connected to the main chassis by using slots and tabs such that when the cover is in place upon the computer, then the subchassis is secured therein. The subchassis and the computer components disposed thereon thus form a module which is conveniently removable and replaceable such that those computer components most frequently requiring service is quickly removed and replaced by a person unskilled in computer repair.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
126 words
A modular computer comprising: (a) a main chassis; (b) a motherboard disposed upon said main chassis; (c) a subchassis removably attached to said main chassis; (d) at least one failure-prone component disposed upon said subchassis; (e) a first electrical connector disposed upon said main chassis in electrical communication with said motherboard; (f) a complimentary second electrical connector disposed upon said subchassis in electrical communication with said at least one failure-prone component; (g) wherein said first and second connectors mate when said subchassis is attached to said main chassis such that electrical communication is provided between said motherboard and said at least one failure-prone component; and (h) wherein easy removal and replacement of said failure-prone component is facilitated by detachment of said subchassis from said main chassis.
Claim 2
Dependent Claim
126 words
A modular computer comprising: (a) a main chassis; (b) a motherboard disposed upon said main chassis; (c) a subchassis removably attached to said main chassis; (d) at least one failure-prone component disposed upon said subchassis; (e) a first electrical connector disposed upon said main chassis in electrical communication with said motherboard; (f) a complimentary second electrical connector disposed upon said subchassis in electrical communication with said at least one failure-prone component; (g) wherein said first and second connectors mate when said subchassis is attached to said main chassis such that electrical communication is provided between said motherboard and said at least one failure-prone component; and (h) wherein easy removal and replacement of said failure-prone component is facilitated by detachment of said subchassis from said main chassis.
Claim 3
Dependent Claim
27 words
The modular computer as recited in claim 1 wherein said at least one failure-prone component comprises at least one of a power supply and a disk drive.
Claim 4
Dependent Claim
41 words
The modular computer as recited in claim 1 further comprising a cover disposable over a substantial portion of said main chassis, said subchassis being secured to said main chassis by said cover when said cover is disposed over said main chassis.
Claim 5
Dependent Claim
38 words
The modular computer as recited in claim 1 wherein: (a) said at least one failure-prone component comprises a power supply; and (b) further comprising a switch disposed upon said subchassis for turning the modular computer on and off.
Claim 6
Dependent Claim
154 words
A modular computer comprising: (a) a main chassis; (b) a motherboard disposed upon said main chassis; (c) a subchassis removably attached to said man chassis; (d) a power supply and at least one disk drive disposed upon said subchassis; (e) a first electrical connector disposed upon said main chassis in electrical communication with said motherboard; (f) a complimentary second electrical connector disposed upon said subchassis in electrical connection with said power supply and said at least one disk drive; (g) wherein said first and second connectors mate when said subchassis is attached to said main chassis such that electrical communication is provided between said motherboard disposed upon said main chassis and said power supply and said at least one disk drive disposed upon said subchassis; and (h) wherein easy removal and replacement of said power supply and said at least one disk drive is facilitated by detachment of said subchassis from said main chassis.
Claim 7
Dependent Claim
154 words
A modular computer comprising: (a) a main chassis; (b) a motherboard disposed upon said main chassis; (c) a subchassis removably attached to said man chassis; (d) a power supply and at least one disk drive disposed upon said subchassis; (e) a first electrical connector disposed upon said main chassis in electrical communication with said motherboard; (f) a complimentary second electrical connector disposed upon said subchassis in electrical connection with said power supply and said at least one disk drive; (g) wherein said first and second connectors mate when said subchassis is attached to said main chassis such that electrical communication is provided between said motherboard disposed upon said main chassis and said power supply and said at least one disk drive disposed upon said subchassis; and (h) wherein easy removal and replacement of said power supply and said at least one disk drive is facilitated by detachment of said subchassis from said main chassis.
