Hey,I am a student at a school and the work I do requires some good hardware because I do things like CAD,software etc,and a shop near my house(its not a random one at that,in my city its a very well recieved one)and I saw these deals(keep in mind theyre used but in very good condition since I saw them on the shop while I was browsing for an option.I need your help in as is which is best:

HP Z2 G5 Workstation i7-10700K, 32GB RAM, 1TB SSD, NVIDIA Quadro RTX 5000 16GB(price is relatively $1300)

Intel Core i5-14600KF | RTX 5060 Ti | 32GB DDR5 | 1TB Gen 4 SSD " MICRO STATION(price is relatively $1100) !BRAND NEW!

These are the two I saw but I have been thinking if I should maybe get a ThinkPad since theyre not too expensive,this was the best option in the store:

Lenovo ThinkPad P15 Gen2 CPU i9-11950H | 32GB RAM,512GB SSD,RTX A4000 Mobile (price is relatively $1000)

Now my biggest concerns are should I get a rig and buy the rest of the components or buy a laptop and just end it at that?A laptop is portable too.

Detailed answers would be greatly appreciated since I would know in depth. 😄
