z240 is not quite cost saving. At this time, nuc9i7 is a better choice. a nuc9i7 with 9750H computing card, some RAM and M2 SSD, then with a HX30 will be enough for your requirement. I recently upgraded my home theater computer from e3-1245+gtx970 to this system, it's far smaller than the 10L Lianli tu100 case, and the cooling is better.

missing fans and shroud so you cannot recognize it.

Actually it depends on how much 12V output is. An average RX570 use a mean power draw about 180W to 200W, and some peak power draw will be less than 300W. Some decent 400W PSU will have about 380W output on 12V, counting that non-k 2400 i5 normally consume a mean 65W, it will be sufficient. Even if you have a gold 300W with 290W 12V output, the system will keep up. But for example an Antec VP450 only has 368W 12V output, and it's a name brand at that time, you shouldn't blame GPU vendor claiming a requirement of a 500W PSU.

I think you mean you want to get the battery out first to get the type of the battery you need to buy, and do not intend to put it in until you get the new one. I'm not familiar with DELL's commercial line, but HP is able to plug in adapter without battery attached.

the RTX A2000 fits you. it's an RTX3060 laptop on an LP PCIE card and consumes 70W which needs no 6pin or 8pin

I think it's wiser for you that you budget for full usage all day for the first available period. Then setup a plan based on actual usage data. When budgeting conservatively, it's less likely to encounter issues unexpectedly, and you can also benefit in cost-down solution based on actual usage data.

But Google cannot mark the order "finished" since the transition is failed. You cannot leave your customer to your supplier. The customer has contract with you not your supplier, and you failed to fulfill your part no matter what reason it is.

The 3060 still equipped with a 6gb vram. 1060 already support vram compression which is helpful for vram. A full power 1060 laptop is no worse than an average desktop 1060. For VR headsets, if you take VIVE for reference, 1060 even on laptop is capable for medium to high preset. You need to understand that most power consuming 3A games do not support VR. Those providing VR will make the medium preset running well enough for 1060. I'm not selling 1060, but just taking this for a reference. Anything newer and equivalent should be sufficient. And anything above that will have significant cost increase while the image quality may not be much, at least will not be as much as you see in the traditional screen.

3060 is overkill. normally a 1060 laptop or anything equivalent performance will be sufficient for medium quality for any VR games. If you accept a minimum low quality, even a 1050 or 1050ti can run most lightweight games.

It will, eventually. It depends on how people's old micro-B, or even older mini-USB devices are consumed, and depends on how often people re-route their desks/workbench.

your story is least like to happen. Although T580 is plastic finish on C-body, there is cast magnesium frame inside to mount motherboard. This frame is super rigid. DELL and HP also use this kind of material for highend commercial laptops. But I know some of the reason that can cause failure. I know that T460 has very stupid design that memory slot is right on touchpad area where the magnesium frame is not covered enough. When you apply a big amount of force through one finger at certain palm rest area, it will cause memory slot connectivity issue and cause blue screen. Lenovo then added a very thick metal pad on D-body to reinforce the area. The palmrest test is actually a very common situation in office use when you are presenting something while you need to change a conference room. All the major companies have the design knowledge and test method to meet the requirements. For your T580 story, I think you should find other root causes other than suspect the palmrest condition.

to me, it's a "must have" feature. without it, I'll change to another option until no phone in the market then repair the existing ones.

What you are selling is literally "used". You do not have a package. You cannot provide invoice from your own business. Your parts are retail parts and every single ones are "out of box".

I have learnt to unplug before close the lid anyway...

Actually, the cells are connected in serial to get a higher voltage for example 12V or even 19~20V. A Li-ion cell is normally 3.7V to 4.2V. In order to make it suitable for the desired voltage, they are serial. So, less cell means lower failure rate.
