New computer

[filip76]

I tried to run KVM on my desktop in the past, but with no luck. I can't tell what went wrong. I probably explained it to myself with the hardware limitation of my computer.

No, I certainly don't plan a virtual machine farm. So far, I have used VBox to test other systems, such as FreeNAS.

Due to the fact that my laptop, or in fact my wife's laptop - the old Toshiba Satellite with Windows, is becoming less and less usable - and the attempt to replace the RAM was not fully successful - I decided to start a discussion here whether or not to speed up the replacement of my desktop

OpenSUSE will definitely remain my main system and Windows will run in a virtual machine. There is also a dual boot option - because of the wife who wants to have easy access "to the computer"

Although in one of the first threads I wrote about buying a laptop with Windows only and switching to this platform, the strength of habit (or maybe laziness) keeps me with OpenSUSE

[karlmistelberger]

You're right, I don't have an SSD. I had the previous, small Transcend - 32 GB but I replaced it a few years ago with a 2.5 "HDD - and I forgot about it [facepalm]. I was convinced that it was an SSD ...

Regarding the mITX board - this is my chase - CHIETEC BT-02B. There is a choice - the old housing and searching among mITX boards or adding the housing to the shopping list.
In the store where I usually buy electronics, many items are unavailable. This applies to the cheaper ones. For example, MSI MEG Z490I UNIFY is available.

In turn, mATX is available twice as cheap MSI MAG B560M BAZOOKA, so for the price difference I can buy a new chase.

These are just two arbitrary examples of motherboards, what is your opinion on this?

What processor would you suggest? i5 10th gen will be enough?

Considering the option with the Dell Latitude 7490 laptop, I could buy it for about $ 600 (Intel Core i7-8650U 16 GB / 256.00 GB). For $ 80 I could buy a docking station, for another $ 80 a battery, and for 130 - a 1TB drive. So for the equivalent of $ 900, I could buy a laptop.

We can consider $ 900 on the top of my desktop upgrade budget, although I'd rather spend less, say $ 600.
I would need:
- motherboard
- processor
- RAM
- chase (if we change the disc format to other than mITX)


Edit:
I did not include a cooling paste or a Windows license in my list, but the license is not urgent as long as I still have an old laptop.

I certainly do not need a DVD because I have, I would also buy an SSD drive, but only for the system and at / home, taking into account the processing of photos and videos, 250 GB should be enough to save projects, ready films and photos would be stored on the HDD.

For discussing the parts list I choose Mindfactory. Components are available from many vendors which may have better offers.

Hi,

I am wondering about one point. I assumed that in the most likely scenario I would install OpenSUSE as the main system and Windows in a virtual machine.

Thanks to this, I would use the computer as before, starting Windows if necessary.

But when buying a used computer, as suggested here, I would most often have Windows installed (often in the Pro version).

In this situation, the option with a virtual machine becomes more difficult for at least two reasons:
1) technical - how to get the system image from the recovery partition?
2) legal - if I understand the information from Dell support correctly - 1 computer = 1 system installation; so Windows can be installed either on disk or in a virtual machine.

Forgive these trivial questions, but the last Windows system that I worked with with administrator privileges was Win XP (then only Linux privately, professionally - Windows without root privileges).
What would you do in this case, assuming you paid for the Windows license with your computer?

1) Option with virtual machine, download Windows from Microsoft website and register in virtual machine with original product key (which I suppose I will get with computer)? What about the Recovery partition - is it justified to keep it (e.g. for later resale?)? Will it work?
2) Dual boot - it seems to be the simplest but the least elegant option. I assumed that I would use Windows sporadically (for iPhone syncing with iTunes and Garmin eTrex). But perhaps Windows Pro should be used for other purposes?

In such a situation, keeping my existing HDD with data, I would have a difficult access due to the file system - ext4 and encryption of some partitions.
Besides, working more on Windows, I would have to run an SMB and DLNA file server on it, and the files are on ext4 partitions.
Yes, there is an option to transfer data to the Windows partition when replacing the disks with new ones, but I would not like to increase the cost of buying a computer with the cost of new disks.

3) Setting Windows as the root system, OpenSUSE in a virtual machine. Is it possible to clone a host computer (OpenSUSE) to a virtual machine (OpenSUSE), perform a snapshot and then run a snapshot in Windows?

Which of these ideas makes the most sense to you? I know that it is best to verify it in practice, but before spending money, it is worth thinking twice
I emphasize that at my age, the war of systems does not matter to me anymore, but I care about obtaining certain functionalities and comfortable use.

Last question - is the antivirus program "must have" in Windows?

Thank you and best regards!

With a modern SSD the default openSUSE partitioning works best. Swap is optional. I have RAM instead:

What would you do in this case, assuming you paid for the Windows license with your computer?

1) Option with virtual machine, download Windows from Microsoft website and register in virtual machine with original product key (which I suppose I will get with computer)? What about the Recovery partition - is it justified to keep it (e.g. for later resale?)? Will it work?
2) Dual boot - it seems to be the simplest but the least elegant option. I assumed that I would use Windows sporadically (for iPhone syncing with iTunes and Garmin eTrex). But perhaps Windows Pro should be used for other purposes?

In such a situation, keeping my existing HDD with data, I would have a difficult access due to the file system - ext4 and encryption of some partitions.
Besides, working more on Windows, I would have to run an SMB and DLNA file server on it, and the files are on ext4 partitions.

Hi
MS Windows is a free download, no need for recovery images (unless your wanting the carp ware), there might be a need for some driver downloads, but most are found by windows...

If the machine has a license, then good to go with either physical and/or virtual AFAIK and activation is automatic..

I have a physical WinX available as well as WinXI in a virtual machine. Use neither much...

Thank you very much for your opinions!

Ok, I think a lot depends on the equipment supplier and warranty records, for example Dell. When buying a new Dell computer, I would rather go with a multi-boot boot. By the way - I became interested in the ready-made Dell Precision 3450 i5-10505 / 16GB / 512 / Win10P desktop (Intel® W580 chipset).

It is different when I build the system myself and download it from the site as you propose.
In this option I would compose something according to the Karlmistelberger proposal, or buy something ready, for example Lenovo IdeaCentre 5 i5-10400 / 16GB / 512 (no OS, Intel B560 chipset).

What works best for many users is multi boot:

...

As I mentioned above, if I would significantly exceed the budget, for example, buying such Dell, I would rather choose a multiboot. My wife, who may partially contribute to the costs, would prefer Windows to start when the "power" button is pressed.

Choosing a cheaper hardware option, i.e. assembling a computer according to your proposal (thank You very much again) or buying a ready-made one (and without my wife's financial contribution), I would prepare it to be convenient for me, i.e. Windows in a virtual machine. Rather

Best wishes!

In the end-user area, finished PCs are generally not recommended because there has been a race to the bottom. Build the PC yourself or specify to a local PC shop exactly which parts should be put in, and don't leave anything unspecified.

even though it appears you are more into virtualizing this alternative non-posix system, please have look at the following thread:

Thanks for the warning! I thought about a finished computer, because they actually look a bit cheaper with similar parameters (Lenovo). In the case of Dell (which is well above my original budget), I thought that maybe I have been using Linux unnecessarily for so many years ...

Thanks for the tip, but I should change my computer more than once in 10 years
