Is this a good computer build?
You have two choices: Aluminium or steelDo not use stainless steel, as its properties are not as good as common steel, so that it will be heavier for the same strengthSteel is for sure the cheapest choice and easier to work with (easy to solder)Aluminium will give you a light and strong structure but costs more.
If you have the time and resources, I would suggest making prototypes of both materials and testing them with stress tests like crush and flex ratesMake a basic frame of both first and see which, of not if both, can support your requirementsBe sure to go well over the expected weight though for safetyIf it is just strong enough, it may very well prove unsafeAfter you reinforce it as needed, weight the two and see what works bestYou would also do well to test each joint and connection you make with scrap bits first and stress test each weld for weight baring abilities, this will save you resources in the long run and improove safety and qualityGood luck!!!!!
Depends on what you are capable of doingCan you weld steel? If so use thatCan you work with aluminum? If you have it and can work with cutting, fastening etc the aluminum will be best due to weight of courseWhat is the rest of your design? If the weight of the frame is a large percentage of the total weight then you will gain using aluminum for its strength to weight ratioIf the frame is a small percentage like less than 30 percent of the total then it wont matter and steel might be bestSteel shapes and accessories will be more commonly available and less expensiveMost likely you are not going to be so cutting edge that using aluminum over steel will gain you anything so my guess is steel will be much easier overall.
Yo he comprado de muchas veces ordenadores en los sitios cyber web y siempre he encontrado lamejor calidad, el ultimo ordenador es para una amiga, laverdad es que parece especial creado para ella porque tiene un disco duro con una excelente capacidad de almacenaje y va bastante rápido por su gran memoria y su buen procesador, muy buena compra sin duda.
