I'm an avid collector of computers and vintage computing hardware, some of my projects are chronicled here.
My main system, called Amadeus, is an heirloom gaming system with an AMD FX-8350 and an Nvidia GeForce GTX 650Ti BOOST. It runs Arch Linux, and I have it set up with i3wm. It features a wide assortment of storage, spread across two SSDs and two HDDs. I like to play with weird filesystems on it, so each partition has a filesystem specifc to its function. My backup/storage/media drive uses XFS for example, due to its ability to handle large datasets well. My root uses JFS, since it's able to continue operating even on highly depleted resources. Since using JFS I've found out that it has actually several flaws for being used as a system root. Namely the filesystem sometimes loses the /usr/share/man/man3 folder, which is spooky to say the least. If I were to redo things I might use BTRFS or EXT4 on that drive. I may actually have to migrate at some point soon.
Comet, my laptop is a very old beast that really needs replaced. It's an Acer Aspire E15 with an AMD E2-6110 APU, and all the hurdles that come with that. I have it running Arch Linux and i3wm, as ever. It struggles with just about everything and really needs to be replaced. Obviously I'd like a Framework or a Thinkpad, but I'll probably not get so lucky digging around as I usually do. This lack of power has led to me discovering some interesting left-field applications like the terminal emulator Sakura, which wraps vte3. It winds up being lighter than something like Kitty, since the E2-6110 has just a horrid OpenGL implementation. While not my favorite emulator to use, it's pretty alright on something like Comet. I've often considered putting some Wayland-based environment on there as well, either Sway or Labwc, but nothing too quickly.
My server/NAS is a slightly modified Dell Optiplex 3020 with a 1TB HDD and runs Alpine Linux. It runs some local services including Soft Serve, Gohpernicus, and OpenSSH. I end up using it to compress my backups using lrzip, and an external HDD. It ends up having limits because of its chassis. Being a low profile case means expansion isn't really a possibility and I'm looking at upgrading it sometime soon.
My first custom build, while it hasn't actually been together in about a year is still around. Its name is Rigger, and it is a Pentium 4 (2.4GHz) that runs MS-DOS 6.22, among other OSes. It has a Riva TNT2, and a SoundBlaster PCI. Construction wise it's sort of interesting because it's an open air case design that I put together myself. It's basically a motherboard screwed to a table with organ felt between the PCB and the plywood for impact dampening, not that it needs that. The system is technically capable of running an OS as sophisticated as WindowsXP, but I would never subject it to something like that. It's probably more suited to something like Alpine Linux or a BSD variant. I actually don't know too much about those operating systems. I have some friends that should be able to tell me about them though.
I also have an old socket 7 rig that I've put together. It features a Cyrix 6x86 @ 150MHz in a PA-2005 motherboard, 32MB of EDO, and 32MB of PSRAM. It has a Matrox MGA Millennium, a SoundBlaster AWE64 Gold, and a few other odd expansions. This system is highly limited due to its CPU. The Cyrix processor can only handle very simple tasks under Windows. That's Windows98 to be clear, even though the system is better equipped to deal with DOS than anything else. There's a number of problems with this machine and some of them I can't fix right now. For one the chipset is having some nebulous problems, probably related to the power supply, and it's causing the BIOS to frequently lose its settings and drain CMOS batteries really quickly. It's also the second system I ever put together. This system is honorably dubbed "Takane", after a late friend of mine who passed to cancer.
