Description

TECHNICAL FIELD The present disclosure relates in general to information handling systems, and more particularly to a door to enable servicing of a heat capture cabinet comprising one or more information handling systems. BACKGROUND As the value and use of information continues to increase, individuals and businesses seek additional ways to process and store information. One option available to users is information handling systems. An information handling system generally processes, compiles, stores, and/or communicates information or data for business, personal, or other purposes thereby allowing users to take advantage of the value of the information. Because technology and information handling needs and requirements vary between different users or applications, information handling systems may also vary regarding what information is handled, how the information is handled, how much information is processed, stored, or communicated, and how quickly and efficiently the information may be processed, stored, or communicated. The variations in information handling systems allow for information handling systems to be general or configured for a specific user or specific use such as financial transaction processing, airline reservations, enterprise data storage, or global communications. In addition, information handling systems may include a variety of hardware and software components that may be configured to process, store, and communicate information and may include one or more computer systems, data storage systems, and networking systems. As processors, graphics cards, random access memory (RAM) and other components in information handling systems have increased in clock speed and power consumption, the amount of heat produced by such components as a side-effect of normal operation has also increased. Often, the temperatures of these components need to be kept within a reasonable range to prevent overheating, instability, malfunction and damage leading to a shortened component lifespan. Accordingly, thermal management systems including air movers (e.g., cooling fans and blowers) and liquid cooling systems have often been used in information handling systems to cool information handling systems and their components. Some thermal management systems utilize air movers and liquid-cooled heat exchangers (e.g., a radiator with liquid-cooled cooling coils). Further, information handling systems may be housed in a cabinet configured to hold a plurality of modular information handling systems and other components, such as air movers and liquid-cooled heat exchangers. One type of cabinet that may be used to house information handling systems is known as a heat capture cabinet. A heat capture cabinet may be a thermally self-contained cabinet in which the air inside the heat capture cabinet is predominantly isolated from the air outside the heat capture cabinet. Thus, as opposed to traditional approaches in which cooling air is drawn into a cabinet by air movers from space external to the cabinet and also expelled into the external space, airflow may be recirculated in a heat capture cabinet such that the cabinet captures as much waste heat energy as possible from the information handling systems therein. Accordingly, with heat contained within the enclosure of the heat capture cabinet, facility cooling costs of a building housing the heat capture cabinet may be minimized, or in some instances, heat capture cabinets may enable use of facilities without air conditioning, provided they have a sufficient supply of coolant (e.g., water) for cooling the heat capture cabinet. In some heat capture cabinets, a cooling coil and air mover unit may be integrated within a service door at the rear of the server rack, wherein such door may be accessed for servicing components residing within the heat capture cabinet. While existing room-exit rear door heat exchangers are currently designed to clear one another when opened, when the necessary enclosure is added to an existing cabinet to enable air recirculation within the cabinet, the total rear door enclosure may get wider and/or deeper and may no longer be opened side-by-side with another heat capture cabinet using a conventional door hinge. SUMMARY In accordance with the teachings of the present disclosure, disadvantages and problems associated with servicing of a heat capture cabinet housing information handling systems may be reduced or eliminated. In accordance with embodiments of the present disclosure, a cabinet may include a rack configured to house one or more information handling systems and a door assembly comprising a box mechanically coupled to the rack in a fixed position relative to the rack and a door rotatably coupled to the box via an offset hinge, such that when the door is in a closed position relative to the box, a gasket is formed between the box and the door. In accordance with these and other embodiments of the present disclosure, a door assembly configure
