开篇语：
关于标题：
标题这么长这么怪,是因为我把所有显卡关键词都塞进去了，以期望new bing可以检索到这篇文章。
原因：
本人是装机小白，近闻AI甚火，决心配一台AI学习/深度学习的主机，学习AI。
但是我对于装机一窍不通，而且这边的人工费太贵了。遂买了GPT PLUS ，进行纯AI装机（即售前咨询，硬件选配，硬件组装等等所有装机的流程全部咨询AI，根据AI的建议购买（即AI出建议，我出钱））。
现在装机成功就差个显卡了，但是每当我询问new bing 40系列显卡尺寸是否能塞进我的机箱的时候。AI因为检索不到数据，每次都说该系列显卡没上市，无法给出回答。
这不就完犊子了，我啥也不懂，这不给回答，都不知道买啥显卡好。
因此，根据以往经验，AI的回答部分根据某乎回答的，但也有一部分根据b站专栏回答的，所以我将搜索到的部分40系列显卡尺寸数据，全部写下来放到某乎和专栏上，以期望可以成功被new bing 检索到，以便顺利完成装机。
这就是为甚么标题这么怪，见谅！

补充：
ps: 单位有的只有英寸因为网站数据就只有这个，无我无关嘿嘿
ps：小白装机一定不要上来就上itx机箱，过于折磨人，切记切记，我属实是被ai坑惨了
ps：4070Ti的数据比别的多是因为我倾向于选择这个显卡（itx机箱装不下大显卡的痛苦啊。。。）
