Update Jan 7, 2022: Today I tried an SSD Cache program to see if it would speed up my 980 SSD and guess what, it did. However, (and this falls under the there is no free lunch category) the caching program slowed down the system memory significantly (From 75th to 60th percentile using Passmark) and actually made my system noticeably slower. I have 16g memory so this should have been enough. Remember, memory is used all the time and the SSD only when necessary.Update January 4, 2022: I recently installed a Samsung NVME M.2 PCIe SSD hoping for improved performance; didn't happen. Seems that Samsung Magician will use "Rapid Mode" on the 860evo but not on the 980. BummerUpdate August 2, 2021: I added  security cable because this PC is so portable. I got a decent one from I can't say the name, but it begins with W, for 4.99 with free shipping. It has a 4 digit combination and a fairly long steel cable. The added security is well worth this cost.Update July 21, 2021: Really fast and responsive PC. My only complaint is the fan can be noisy. I did buy the dust filter for this system directly from Dell; for only $10 I feel it is worth it to keep the processor heat sink and the rest of the PC free from dust. The part number for this filter is 5PC6W and Location is 170405 direct from Dell. Download "Dell Support Assist" app, really easy to keep the pc running like newMine came with 9 months left on the original warranty so you might want to check with Dell on yours.Update July 14, 2021: New power supply came and fixed everything, OK so I still am not rich, but the computer is a real hummer, very responsive. The supplier came through with the correct power supply very fast. I would work with them again in a heartbeat.Supplier is great with customer service, not so great with QC of shipments. For a second time they shipped incorrect power supply. They are, however, really great at listening to the customer and correcting the problem.As to the PC itself it is good, but will be great once I receive the correct power supply. Also, please go to the Dell service website and install all of the driver updatesMine shipped with a 2.4g WIFI USB adapter, not great if you need 5g. This is no biggie for me as I only use Ethernet. and I returned this one.I am running now with a 90 watt power supply instead of the correct 130 watt so my processor is running at only 0.79 gig instead of 3gig because  the processor is automatically throttled in this situation, The supplier has sent out the correct power supply, like I said they are very responsive to the customer's needs.Even so the pc is quite responsive, I can hardly wait to see what it is like at the correct clock speed.I think I lucked out, the unit I received has an i5-8500 processor, not the i5-8600T advertised. This processor requires a 130W power supply and is potentially 20% to 30% faster. than the i5-8600T.Watch this space - I will return here later with an update when I get the new power  supply,
