if you post pictures of all the connectors on here then we can tell you what needs adapting i transplanted an optiplex into a standard mATX case but i had to custom-splice the power button, frontpanel, and use adapters for the fan headers

late Xserves are EXPENSIVE this is because they were on the Hardware Compatability List for vmware ESXi so all the businesses that wanted to legally run mac VMs bought up all the XServes. an equivalent spec HP/Dell/IBM server will be half the price

You should certainly Overclock your 9700k it’s the whole point of the K series. will it make your 4K gaming perfect? Probably not. will it make everything a bit faster? yes

Dell optiplexes use custom headers for things like power button, frontpanel and stuff like that. Maybe inspiron is the same. Open yours up and take a look at all the connectors and confirm you have the ability to plug them into standard ATX things.

A vm you’ll attach to a portgroup which you’ll configure to attach to a physics nic.

Old enterprise servers like the hp dl360 or dell poweredge should be found for very cheap. a gen7 DL360 is basically worthless to a business, we pay to have them thrown away. Look on google for a local company that buys second hand enterprise IT as they’ll have some old stock they’ll sell for cheap

the 2850 is Super Super Super Old. I pay people to take away stuff that's 10 years newer than that. 2008R2 removed support for the PERC4e. you'll need to use original 2008 or 2003 https://www.dell.com/community/PowerEdge-OS-Forum/Windows-Server-2012-on-PowerEdge-2800/td-p/3978790 which again, is so damn old whats the point.

as above. usually the switching side of it will be basically the same as this is easy peasy for the switch engine, what makes all the difference is the routing part. so PC1 connected via cable to PC2 will likely get full speed all day long on any cheap crap. when it comes to Wifi, multiple users, good features, fast WAN etc. this is where the differences really come into play

look at the ethernet port up close. do you see any missing/bent/damaged pins? have you tried a different cable or a different PC plugged into the same cable? my money is on a physical fault meaning you cant use all the pairs in the cable and so stuck at lower speeds (10baseT uses less pairs than 100/1000baseT

what lengths are we talking about here? assuming it's not particuarly long, i'd assume the issue is with the termination. ie it's FAULTY cable can be bad, but it's pretty rare if its off a new reel. as the last guy said, cat5e is good for gigabit ethernet at 100m

vote with your feet as they say. basically, switch to a provider that doesn't do this if you don't like it.

basically what hes currently doing is the best most effective and SIMPLEST way of doing it. i'd reccomend he carries on doing what hes doing

whats the context, is this a business, landlord, dormroom? are these customers or friends? what everyone has said above is correct so no need to repeat. the simplest option is to just say "no you cant have an inbound connection" and be done with it, as getting that working will require some level of networking knowledge and to do it auto-magically for people even more so. if you can find a wired router with 8 100/1000 ports on it that'd be idea. as you wont need a seperate switch

it should show up in device manager even if no drivers as unknown device. drivers will be found on dell website or broadcom website. why do you think you need a PCIe nic tho?

10gigabit networking isn’t really a thing for home setups especially to end user devices. Switches for this (that aren’t junk) are very expensive. as for the point about CCTV on a main network switch, with a managed switch you can actually run many seperate virtual LANs on the same switch with segmentation so your main network cannot see the cctv network etc. This is the sort of thing that’s commonplace in the workplace where you have different users/devices with different levels of trust. Any managed switch can do this

second hand old enterprise gear is REALLY GOOD VALUE. for example you can get a Cisco 3750 switch for under £100 that'll have every feature you'll ever want and probably never break. These things cost £5k+ when they were new. Tons of companies deal in old networking gear, cisco kit is even traded like a commodity! but they'll be noisy, heavy, and you'll need to learn some basic network skills to get them up. not sure if that's something you're interested in or not, just bear it in mind.

people generally dont seem to realise how much CPU horsepower it takes to do a VPN over a multi hundred megabit connection especially on older hardware that didnt have dedicated encryption offload. try reducing your encryption level to, well... none... and do a quick test and then you'll be able to see if this is an issue or not. your best bet to learn more about different technologies on offer is to contact a vendor that provides these solutions (ie a big ISP) and get them to come in and try and sell you things., they can give you the Pros and Cons of different solutions, prices etc. then you get a nice bit of free training. you dont need to buy anything off them

Personally i’d Keep an eye on the second hand market if you’re on a budget. Lots of people selling full systems for cheap that are just a few generations old. for example i recently picked up a full PC with i5-7400, 1060-3gb, 8Gb, Optane+SSD+HDD for £250 building a similarly powerful PC from new parts would cost triple that often you’ll find old PCs from companies that are good spec i5/i7, just add a GPU and you’re sorted. Pc recycling companies are worth looking for. Companies usually pay them to take it away!

What country are you in? UK electronics retailer CEX will buy your 3570 from you for £30 and sell you a 3770 for £90 so that makes it a £60 upgrade. There will be similar retailers in other countries I guess still a fair amount of money to drop on an old platform but worth knowing your options.

Keep an eye out for cheap 3770 chips but be prepared to replace the whole platform. spending any decent amount of money on that platform isn’t good value especially as z77 boards still command strong prices. and don’t spend extra for a K chip, the u locked multiplier is useless to you, if you wanted to bclk Overclockers (and you don’t!) this works the same on a non-k

It’s probably the cooler bunged up with dist. Blow a can of compressed air in the headaink and see how it is then. That’s 100% safe and not taking it apart.

My son’s PC has a 7400 in it on a non-OC’able motherboard and I’ve been on the lookout for a cheap 7700 or 7600 anyone ever gone from a 7400 to anything better and has any good or bad advise? the 7500 seems readily available but guess it won’t be much of an improvement, the 7700 seems pretty pricey and the 7600 seems like a good option I’m just struggling to find a reasonably priced on. plesse don’t comment based on stuff you think/stuff you’ve read I’m looking for practical first hand experience (eg I upgraded from 7400 to 7600 and didn’t notice any difference)

Most Dells use a 6pin connector moddiy.com sell adapter cables I actually have a spare one here I ordered in error, where in the world are you?
